✦ Synopsis

The electronic spectrum of gas-phase tellurium dioxide has been recorded between 345 and 406 nm using the technique of laser-induced fluorescence spectroscopy. The TeO 2 sample was prepared by direct heating of the solid and by seeding it in a continuous free-jet expansion in argon. Twenty-seven cold bands and thirty-two hot bands were assigned. The wavenumbers of the band origin and symmetric stretching and bending vibrational modes for the upper and lower states were determined in a simple least-squares fit: 0 ϭ 25526 cm Ϫ1 , Ј 1 ϭ 679 cm Ϫ1 , Ј 2 ϭ 220 cm Ϫ1 , Љ 1 ϭ 823 cm Ϫ1 , Љ 2 ϭ 282 cm Ϫ1 .

The electronic spectrum of NiCN in the 500-630 nm region has been observed by laser-induced fluorescence, following the reaction of laser-ablated nickel atoms with cyanogen under free jet expansion conditions. Seven electronic states have been identified. Three of these, X1 2 5/2 , X2 2 3/2 , and W1
