摘要：

Potential curves of the SH, KrH and KrS molecules needed for the diatomics-in-molecules (DIM) treatment of the ground and excited states of the SH(X,A)... Kr complex have been computed at the SOCI/CASSCF level. The ionic and ion-pair states of these diatomic fragments which play an essential role in the DIM model of intermolecular interactions have been considered as well. The new results for the ion-pair states of SH are compared to the corresponding data for OH. The curves for KrS and XeS [M. Yamanishi, K. Hirao, K. Yamashita, J. Chem. Phys. 108 (1998) 1514] are discussed. The main features of the empirical potential surfaces of the SH Kr complex are reproduced by the DIM technique. (C) 1999 Elsevier Science B.V.
