✦ Synopsis

The lowest quartet states (a^{4} \Pi) and (b^{4} \Sigma^{-})of the antimony monoxide radical have been observed in LIF excitation spectra measured with a pulsed dye laser in the wavelength range (335-640 \mathrm{~nm}). Transitions from the (X_{1}^{2} \Pi_{1 / 2}) ground state to three spin-orbit components of the (a^{4} \Pi) state ( (\Omega) (\left.=\frac{3}{2}, \frac{1}{2},-\frac{1}{2}\right)) and one component of the (b^{4} \Sigma^{-})state (\left(\Omega=\frac{1}{2}\right)) have been identified. Vibrational analyses of the spectra have yielded the following molecular constants of ({ }^{121} \mathrm{SbO}) ( in (\mathrm{cm}^{-1}) ):

Lifetime measurements of the A 4 P, B 4 P, and C 4 S 0 electronic states of the vanadium monoxide molecule were performed using population probing of resonant two-photon ionization in a molecular beam. These lifetimes were found to be 6 { 1 msec, 0.37 { 0.05 msec, and 73 { 2 nsec, respectively, for

A laser excitation spectrum of the (0, 0) and (1, 1) bands of the CaF A 2 ⌸-X 2 ⌺ ϩ system was recorded. The present set of molecular constants for both A 2 ⌸ and B 2 ⌺ ϩ states represents a vast improvement in precision over previously reported values because of the larger number of line position m

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
