✦ Synopsis

The spin-orbit excited 2113,2 manifold of " BAriX 'II) was observed in a free jet supersonic expansion by laser fluorescence excitation in the B ax'-X 'II (7, 0) band. In previous work we observed transitions from the lower 'II ,,?_ manifold. The spin-orbit constant A was determined to equal 10.88 f O.O8(la) cm-', close to a simple estimate, $AE= 10.17 cm-', where AE is the boron 2p 'Pa,,-'P ,,z spin-orbit splitting. The near equality of experimental and theoretical values of A suggests that the boron 2p orbital is not strongly affected by the weak, nonbonding B-Ar interaction.

Stimulated emission spectroscopy is used to measure the frequencies of the van der Waals bending and stretching modes in the ground electronic state of the OH-Ar complex correlating with OH(X 'II) +Ar( 'S,). The results are compared with those predicted using an ab initio potential energy surface. E

Configuration selection methods for multiconfiguration (MC) SCF wavefunctions have been applied to the van der Waals X 'Z+ ground state of LiHe. The configuration selection was restricted to "dispersion" configurations, corresponding to simultaneous single excitations out of each atom. Energy loweri
