THEORETICALLY CALCULATED ROVIBRONIC TRANSITION SPECTRA OF KRB

Spectroscopic properties of all the electronic states of KRb dissociat ing into 4s(K) + 5s(Rb), 4s(K) + 5p(Rb), 4p(K) + 5s(Rb), and 4s(K) + 4 d(Rb) and some higher-lying excited states are studied with ab initio calculations. Spectroscopic constants, dipole moments, and the nature of the electronic wave functions for these states are reported. Intens ities for the singlet-singlet and triplet-triplet transitions are theo retically calculated from the potential energy curves and the transiti on dipole moments. (C) 1996 John Wiley & Sons, Inc.
