Explanation of Tables
Material
The chemical formula is required here. Note that this is case sensitive (e.g. CO for Carbon Monoxide vs Co for Cobalt).
Density
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.
Output
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. An encapsulated postscript file is also offered for printing out the results.
