✦ Synopsis

The emission spectrum of gas-phase YbO has been investigated using a Fourier transform spectrometer. Chemiluminescence was observed from excited YbO molecules produced in a Broida-type oven by the reaction of ytterbium metal vapor with N 2 O. A total of eight red-degraded bands in the range 9800-11 300 cm Γ€1 were recorded at a resolution of 0.04 cm Γ€1 . Because of the multiple isotopomers present in the spectra, only three bands were rotationally analyzed. Perturbations were identified in two of these bands and all three transitions were found to terminate at the X 1 R ΓΎ ground electronic state. The electronic configurations that give rise to the observed states are discussed and molecular parameters for all of the analyzed bands are reported.

The vibration-rotation spectrum of CS was observed in emission in the spectral region \(1000-1400\) \(\mathrm{cm}^{-1}\) with a Fourier transform spectrometer. The observed spectrum consists of nine \(\Delta v=1\) vibrationrotation bands with \(v \leqslant 9\). The present data combined with previou
