 Title: VELOCITY MODULATION LASER SPECTROSCOPY OF NEGATIVE IONS: THE INFRARED SPECTRUM OF HYDROSULFIDE ($SH^{-}$) Creators: Gruebele, M.; Polak, M.; Saykally, R. J. Issue Date: 1987 Publisher: Ohio State University Abstract: Twenty-five transitions in the $v=0+1$ and $v=1+2$ bands of $^{32}SH^{-}$, as well as in the fundamentals of $^{33}SH^{-}$ and $^{34}SH^{-}$ have been measured with a diode laser by the velocity modulation technique. The data set was fit to an effective Hamiltonian through sextie terms to determine equilibrium molecular parameters. Comparison with the neutral SH radical shows a strong similarity in the anion and neutral molecular constants, as in the case of $OH^{-}$. The agreement of experiment with ab initio calculations is found to be quite good.
