✦ Synopsis

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 B 1 P ( £ Å 0 -4 ) levels from which equilibrium constants of the states are derived. Perturbational effects are observed in the bands with £ Љ Å 1 that are interpreted as consequences of the avoided crossing of X 1 S / ( £ Å 1 ) and a 3 D 1 ( £ Å 0 ) at J Å 70. A treatment of the perturbation is made using an effective 2 1 2 matrix representation of the rotational energies of the two levels.

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,
