Explanation of Tables

The chemical formula is required here. Note that this is case sensitive (e.g. CO for Carbon Monoxide vs Co for Cobalt).
If a negative value is entered, the chemical formula is checked against a list of some common materials. If no match is found then the density of the first element in the formula is used. If your favorite material is not on the list just drop me a note and we'll add it.
A GIF plot may be generated for quick viewing of the results. If you need anything fancier, the results are provided as a text file for use with your favorite plotting package.
