Dear Computational Chemistry Folks (What is Computational Chemistry, and Who we really are ?) For people interested in kinetics there is a program to solve kinetic equations kindly submitted by Mike Whitbeck from Desert Research Institute. For those not interested in kinetics, the program contains an excellent stiff diferential equations code. The program is really nice and in C. The total size of files is about 200kB. People with ftp access can get it in the following way (assuming you are on unix machine): cd to_the_directory_you_want_kinetics_program_to_be ftp www.ccl.net (or ftp 128.146.36.48) Login: anonymous Password: your_email_address ftp> cd pub/kinetics ftp> get note ftp> binary ftp> get react.tar.Z ftp> quit Then you uncompress and untar the react.tar.Z as: zcat react.tar.Z | tar xvof - (if your UNIX does not allow "o" option in tar, you need to be a root). For those unlucky ones without ftp connection, I made the program available by e-mail interface, since it is small enough to do it this way. Start with sending a three-line message to OSCPOST@ccl.net or OSCPOST@OHSTPY.BITNET send kinetics/note from chemistry send kinetics/list_of_files from chemistry send kinetics/oscpostfile from chemistry Read the "note" file to see if you want to go on. Then (if so), look at "list_of_files" file which lists all the files for this program. Then, EDIT OUT header from "oscpostfile" and send it to OSCPOST@ccl.net or OSCPOST@OHSTPY.BITNET. Now patiently collect the files as they arrive by mail (look at Subject: line which tells you the file name).
