摘要：

An ab initio investigation of the vibronic and the spin-orbit coupling effects in the X2 A', A2 A'' (1 2II) system of HCO is presented. Vibronic energies, intensity distributions within the band progressions, and spin-orbit splittings for levels of different vibronic symmetries are computed. The calculated spin-orbit constant A(SO) is determined to be 69 cm-1, roughly a factor of 2.5 larger than that previously assumed. With this value of A(SO), agreement within 0.02 cm-1 between our theoretical and experimental fine-structure splittings of the lower vibronic levels is observed. (C) 1994 Academic Press, Inc.
