Bartlett from Quantum Theory Project at University of Florida will present a talk "ACES II: A Program System for Molecular Electronic Structure and Spectra" on Tuesday, Jan. 15, 1991, 3:30pm, at Ohio Supercomputer Center, 1224 Kinnear Rd., Columbus, OH 43212-1163, room 405 (classrom). The selection from the announcement follows: Coupled-cluster theory offers some of the most accurate, ab initio correlated results for molecules available. Our new program system, Advanced Concepts in Electronic Structure II provides powerful CC/MBPT methods for energies, structures, vibrational, electronic and photoelectronic spectra, and molecular properties in an extremely efficient, vectorized program. I will illustrate some of the new many-body methods we have recently developed and that are uniquely available in ACES II by considering some chemically interesting problems that could not be solved with other program systems. The primary authors of this program are Bartlett group members: Dr. John Stanton, Dr. Jurgen Gauss, Dr. John Watts, Dr. Magnus Ritthy and Mr Walt Lauderdale. jkl %-% at %-% ccl.net
