Chemistry Nexus

by WebElements: the periodic table on the web

There are many chemical web pages that display chemical structures within the web page itself. You, the viewer can then rotate the molecule on screen, read off bond lengths and angles, and do other useful things. To do this, a free piece of software known as a plug-in is required. There are at least two plugins available for you to use. In practice you will probably need both since they have different abilities and chemistry web site authors often cater for one rather than the other. Both are available for Macintoshes as well as PCs and both are free.

The first available is known as Chime. On a Mac you have to use a NetScape browser in Classic mode while on a PC either NetScape or Internet Explorer is OK. The features available for Chime under MacOS and Windows differ unfortunately.

The second available is known as the Chem3D Net Plugin. On Macs and PCs either NetScape or Internet Explorer is OK.Remember, some of what Chime can do, the Chem3D Net Plugin can not, and vice versa, so I suggest you get both (they are free). Many pages in WebElements benefit from these plugins, so get them and give them a try.

Note: links updated December 2009. The Chem3D Net Plugin seem to be available no longer.

Note: this is pretty much historical as most inline structure display is by packages such as JSmol.
