✦ Synopsis

Laser absorption spectra for the LaF [16.6]0 / -X 1 S / (0,0), B 1 P-X 1 S / (3,0), (2,0), (1,0), (2,1), and (3,2) bands were recorded. Accurate molecular constants and the internuclear distance for the X 1 S / state are presented. Rotational perturbations were evident in the B 1 P (£ Å 1, 2, 3) levels. These perturbations were analyzed and assigned to interactions with the c 3 1 D 1 and [16.6]0 / states. Equilibrium molecular constants for the B 1 P, [16.6]0 / and c 3 1 D 1 states are reported.

Rotational analyses have been carried out on eight thermically excited emission bands of the infrared B 1 P r X 1 S / system of scandium monoiodide between 4000 to 5000 cm 01 , recorded by Fourier transform spectrometry. Rotational constants and energies are obtained for X 1 S / ( £ Å 0, 1, 2 ) and

The emission spectrum of BN has been investigated in the 1800-9000 cm 01 region using a Fourier transform spectrometer. BN was formed in a microwave discharge of He with a trace of BCl 3 and N 2 . The bands observed in the 3000-7800 cm 01 interval have been assigned as the b 1 P-a 1 S / transition,
