  DOWNLOAD ACD Labs ChemSketch

a really convenient structure-drawing program, especially when you're composing a quiz at the last minute!

DOWNLOAD  Adobe Acrobat Reader 4.0

if you don't have it already, you need this to read .pdf documents, which are very common at many  government and university sites.

DOWNLOAD  Macromedia Shockwave™®     or

  you'll need this to play the animations at Mark Bishop's site and others like the Periodic Spiral as well.

you need MDL Chime

CHIME by MDL  follow links

If you can see the structure at the left, you've got it already. If not, you're missing out on the most popular way to view and manipulate 3D pictures of molecules! Head on up to the site and download it now! 

Chime is available in both Netscape and MS IE versions, but the Netscape version is the only one that will work reliably for all Chime sites.
Use Netscape 4.x only [4.75 to 4.79]
-- NEVER the dreadful Netscape 6 [or 7]!!!
My IE 6 version [I have Win XP Pro at work] is working quite well -- for those sites that allow it.

DOWNLOAD  MDL CHIME 2.6x    follow their  links   neither was this one !  

A really useful tool for viewing .PDB files as manipulable 3D images. Available for both MS Internet Explorer and Netscape -- why not get both versions at the same time and make life simpler no matter which browser you prefer? [You'll see my feelings on browsers just a few entries down!!]   

DOWNLOAD    MDL IsisDraw 2.4

Freeware that's really convenient to use.  Draw a structure, select it and copy directly to MS Word™ with no hassles. Different look than with CS ChemDraw™ and ACD Labs ChemSketch™. I used ISIS to do the benzene icon for the organic sites.

DOWNLOAD KnowItAll® Academic Edition from Bio-Rad

"In a continued commitment to academia, Bio-Rad is offering this completely FREE and fully functional software package to promote learning and research in the academic community... draw structures, perform IR and Raman functional group analysis, access a multi-technique spectral database with cross-references, and generate high-quality reports..."
I'll let you know how I like it after I've had a chance to use it....

DOWNLOAD   MS Internet Explorer 5.5

A survey by one British chemsite had MS IE™ a 3:1 favorite over Netscape™  but you need both, for reasons you'll soon see.  Please, Mr. Gates, let's make IE a bit more plugin-friendly --  I'm tired of having to use Netscape to access a handful of really good Chime sites. 

DOWNLOAD  Netscape Communicator 4.75 or 4.76 or 4.77 or 4.79

  4.75 or 4.76 works fine with CHIME -- in fact, for some perverse reason, as explained by Eric Mertz at his World Molecular Visualization site,  many CHIME sites don't work well with MS IE; nonetheless, beware newer Netscape versions, especially the dreaded Netscape 6 !!!!  See further comments under WebCT below.

   DOWNLOAD QuickTime™  Media Player

Another useful program you'll need at some sites

DOWNLOAD Real Player 8,rcahome,011210r1choice_h2,011204rpchoice_c1&dc=121812171216

or go to and hunt carefully for the free download -- it's not easy to find...



Atomic Orbitals by David Manthey at SUNY Albany

Neat pictures of orbitals -- and orbital-drawing software you can download from "Orbital Central"

"Download Orbital Viewer for Windows 95/98/NT 4.0/2000/ME/3.1x (3.1x requires Win32s). 690 kb. This includes a simple help file. Versions for other operating systems are available on the programs page. It is strongly recommended that Orbital Viewer be run on a Pentium computer or better. Last updated 3 April 2001."

ChemCAI   Instructional Software and Other Resources for Chemical Education by Steve Lower (retired) Simon Fraser University

This site has a wealth of resources for chemistry teachers, with an emphasis on computer-assisted instruction. You absolutely have to check it out. You may have noticed that Steve Lower has several entries under various headings in this list  -- that should show how together his act is!

Chem1 Concept Builder™  by Steve Lower (retired) Simon Fraser U

Truly effective and attractive presentations designed to promote real understanding of  a wide variety of fundamental chemical concepts.  You can download a partially-functional tryout version. If you like it as much as I did, the full version is around thirty dollars -- money very well spent!



C4 Computers in Chemistry at Cabrillo College, CA        

a really excellent CHIME site, with tools and tutorials. Unfortunately, you can't get the site to work right with MS Internet Explorer™ even with the IE version of CHIME installed, so access it with Netscape Communicator™ 4.75 or 4.76.

eChem Molecular Modeling Program from hi-ce*

*Center for Highly Interactive Computing in Education at the University of Michigan

"eChem is a simplified and learner-centered design version of professional visualizing tools. It allows students to build and manipulate three-dimensional models of molecules with a visualizer module. It also allows students to compare computationally predicted properties of the molecule with properties they observe in the laboratory. All views and modules are linked together, allowing the student to easily switch between various representations of the molecule."

I've tried it and it really is easy to use. Aimed at a high school audience, it has potential uses in higher ed as well. The lower picture at left shows L-cysteine in ball-and-stick (upper left), spacefill (lower left) and wireframe (both upper and lower right) displays. When the same molecule is shown in all four panels, they can all be simultaneously rotated.


This web site provides a simple service - when you find a page on the web whose address is too long to paste into an email or other document, you can use their free service to generate a shorter, simpler address. You can pass that shorter URL on to others by email, confident that most email clients will recognise it as a URL and turn it into something clickable.

Molecular Origami by Bob Hanson and Ben Murray at St. Olaf College

a program that enables you to pick and choose from a RasMol display only those portions of a molecule that you are interested in.

Parallel Graphics: download Cortona VRML Viewer

even though it  seems that VRML may have passed its peak, there are still scores of great sites out there where you will need a viewer plugin to see the goodies. This one works very well with IE and Netscape 4.7x.

ACDLabs   Advanced Chemistry Development

Makers of really useful software -- some of it available free! ACD ChemSketch, HNMR, CNMR, .... some of it is compatible with CS ChemOffice as well.

ArgusLab v. 3.0 3D Molecule Builder from Planaria Software

You can download a free trial version. I haven't tried it yet, but plan to after I've asked them a few questions. The licensed version is currently $79.95 for academic users and has a long list of features. I appreciated that they have a "known issues and bugs" page [it's quite short].




 Cambridge Software  

 the makers of  CS ChemOffice     [no chemist should be without it!!],
 CS ChemDraw
,  CS Chem3D, CS ChemFinder, CS ChemInfo,
CS ClipArt
, CS MOPAC.......  
watch out for that free Chem 3D viewing plugin -- it may change the way your Chime structures look on MS IE and Netscape unless you load Chime afterward [it's a MIME thing]!


ChemSW software

they distribute a lot of items, including products by Cambridge Software, and have goodies of their own design as well.

online course development in general and organic with free tryout

The Virtuality Project

free demo and for-sale software and web-based instructional aids

WebCT WebCT Chemistry

considered by many to be the premier online course management system; you can get a free tryout, but it's much better if your school signs on and arranges for one of their people to present a training session. In any case, they have lots of resources that are available free. Check it out...

FLASH! on 5/18/01 WebCT issued the following announcement:  "After extensive testing, the WebCT Development Team has determined that the Netscape 6 and 6.01 browsers will not be supported in WebCT 3.6 Standard or Campus Editions. Our testing has revealed that several significant issues in these latest versions of the Netscape browser seriously affect how WebCT content is displayed, and impair the designed functions of some WebCT tools." we're all on the same page where 6.x is concerned!
