Molecular Weight and CHN-analyses, including solvates 
(for Windows)

This program can be used for the calculation of double bond equivalents, CHN-analyses and molecular weights from a given molecular formula. The program also checks on validity of given molecular formulas by a valence sum crosscheck. Fomulas of salts and polymers are accepted as well. The amount of solvates can be estimated by entering found CHN-analyses when differing significantly from expected values.

The program may be freely given away but must not be sold.

As this program is still under development, any suggestions and comments for improvements, corrections, desired additional features or hard- and software incompatibilities are highly welcome. Please use the contact adress given below.


The program is written in VBasic 3.0 and runs with Windows 3.1 or higher. The program is available as a self extracting file or as compressed Zip file on our site.

Please transfer the program molform.exe by clicking on the name and then start the program in a local directory on your site. The program will create the respective files (WinZip needed). The molform.zip must be uncompressed with Winzip and includes the same files as the selfextracting file.


(!) In case you encounter a problem or when you need the program on disc or via email please contact the adress given below by phone, letter, fax or e-mail.
