✦ Synopsis

Polarization labelling spectroscopy of the B 1 ← X 1 + and C 1 + ← X 1 + band systems in KLi reveals strong mutual perturbation of the B and C states. We show that both excited states can be described in a model comprising numerical IPA potentials for the unperturbed states and only 3 parameters to describe their interaction. Our approach allows to identify many previously unassigned spectral lines having significant deviation from the "regular" positions.

Transition probabilities for the B 1 + -X 1 + and the B 1 + -A 1 electronic systems are presented for v = 0-4 and J = 0-150 in each electronic state. The functional form of the electronic transition moment for the B-X transition is taken from published ab initio results. The B-A moment is assumed to

Laser excitation spectra of yttrium monohydroxide, YOH, have been recorded in the 500 -625 nm wavelength region. Rotational analysis of bands of YOH and YOD has shown that the ground state is X ˜1⌺ ϩ , with the structure r 0 (Y-O) ϭ 1.948 6 Å, r 0 (O-H) ϭ 0.920 6 Å; the bending frequency ( 2 , ) is

The results from the separate analyses demonstrate clearly that the two hamiltonian operators are essentially equivalent, both achieving equally satisfactory representations of the spectral data, and furnishing virtually identical Born-Oppenheimer potential functions. Fully quantum-mechanical vibrat
