Velocity modulation diode laser spectroscopy of negative ions: The ν1 + ν2 - ν2, ν1 +ν3-ν3 bands of thiocyanate (NCS-)

Article abstract of DOI:10.1063/1.453030

149 transitions in the ν₁ band (CN stretch) and the corresponding bending and stretching hot bands of thiocyanate (NCS^-) have been measured using velocity modulation spectroscopy with a tunable diode laser.The data were fit to an effective rotation-vibration Hamiltonian, yielding spectroscopic parameters for the ( 000 ), ( 100 ) , ( 010 ) , ( 110 ) , ( 001 ), and ( 101 ) vibrational states.The band origin is ν¹ = 2065.9312(13) cm^-1 and the equilibrium rotational constant is calculated to be 0.197 438(61) cm^-1.NCS^- was prepared in a NH3/CS2 discharge, and unlike the recently studied case of NCO^-, vibrational excitation in excess of the rotational temperature ( 650+/-200 K ) was not observed.
