Molecular dynamics program



 Dear CCL: I got the following e-mail from a friend of mine whose research
 interests is in the field of electrochemistry. Your help is most appreicated.

 	Dear Azhari:
 	I am asking your help regarding our recent research.  We are
 	currently studying the adsorption of some hetero(arylene)s, which
 	are specifically: thiophenes, furans, pyrroles and their derivatives
 	at some solid surfaces.  We are also studying the effect of the
 	substituents on the rings and the mode of adsorption of these moities
 	at the Fe, Al and steel surfaces.  We are requesting a
 	molecular dynamic program that will allow us of studying the
 	interactions at the surface and simulating the configuration of the
 	adsorbed molecules. We prefer that the program to be free.
 	Can I also get any informations regarding the ZINDO program and
 	whether it can be used in our study.
 	Thank you for your help.  Best personal regards.
 	Sincerely,
 	Ahmed
