Moura" [gustavo**mercury.chem.pitt.edu] Dear CCL Readers, last week I sent a message to the list inquiring about a program for performing INDO/S calculations with certain specifications. I have received three suggestions of codes that I am quoting below: 1-Jeff Reimers' (at U. Sydney, Australia) CNDO code which also does INDO/S (http://www.chem.usyd.edu.au/~reimers/); 2-David Yaron (at Carnegie Mellon) has his own INDO/S code; 3-Christopher Cramer has a code called ZINDO-MN for such calculations. Thank you for all the suggestions I have received. Sincerely yours, Dr. Gustavo L.C. Moura gustavo /at/ mercury.chem.pitt.edu ORIGINAL MESSAGE: Dear CCL Readers, I am looking for a program that performs INDO/S calculations and has the following specifications: 1- the program should be able to handle very large excitation windows in the CIS calculations. I have met serious problems with the program I am using right now. When I try to run calculations with large numbers of occupied/unoccupied orbitals the program simply refuses to perform the calculations. 2- the program should print the dipole moments of the excited states and the transition dipole moments between excited states. I want to calculate the nonlinear optical properties of organic molecules and I need these dipole moments in my calculations. Thank you very much in advance for your answers to my question. Sincerely yours, Dr. Gustavo L.C. Moura gustavo /at/ mercury.chem.pitt.edu
