FOURIER TRANSFORM EMISSION SPECTROSCOPY OF ScS

Author Institution: Department of Chemistry, University of Arizona, Tucson, AZ 85721; Department of Chemistry, University of Waterloo, Waterloo, Ont., Canada N2L 3G1; Department of Chemistry and Biochemistry, Arizona State University, Tempe, AZ 85287The emission spectra of the $A^{2}\Pi - X^{2}\Sigma^{+}$ and $B^{2}\Sigma^{+} - X^{2}\Sigma^{+}$ systems of ScS have been observed in the $10000-13500$ cm$^{-1}$ region using a Fourier transform spectrometer. A rotational analysis of the $0-1$, $0-0$ and $1-0$ bands of the $A^{2}\Pi_{3/2} - X^{2}\Sigma^{+}$ and $0-1$, $0-0$, $1-0$, $2-0$ and $3-1$ bands of the $B^{2}\Sigma^{+} - X^{2}\Sigma^{+}$ systems has been obtained and improved spectroscopic constants have been extracted for the electronic states of ScS
