Jensen" Subject: Vibrational analysis w/ constraints Hi, I am interested in doing a vibrational analysis of a Hessian matrix calculated for a system that was optimized with geometric constraints. Can anyone point me to literature of this subject? Thanks, Jan Jensen =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Jan H.
