    • Calculations were performed using the program MOPAC, version 6.0 (QCPE 455) implemented in a Silicon Graphics Workstation. All geometry optimizations involved the keyword PRECISE (criteria for convergence to be increased by a factor of 10-100), and the programs used included the parametrization of S and Br.
