Abstract

Two rotational transitions of the first six vibrational states of three isotopomers of zinc monosulfide, ⁶⁴Zn ³²S, ⁶⁶Zn ³²S, and ⁶⁸Zn ³²S, have been observed in cavity Fourier transform microwave (FTMW) spectroscopy. in addition, the hyperfine splitting of the ⁶⁷Zn ³²S due to the nuclear quadrupole coupling constant of the I = 5/2 ⁶⁷Zn nucleus was observed for two rotational transitions of v = 0. the zinc sulfide was produced by laser ablation of a zinc rod with the resulting zinc plasma reacting with 0.6% OCS in argon in a pulsed jet originating upstream of the ablation plasma. a Dunham expansion of the rotational constant is performed resulting in the determination of B_e, α_e, γ_e, δ_e, and ε_e (Y₀₁, -Y₁₁, Y₂₁, Y₃₁, and Y₄₁) for ZnS. There is no evidence of Born-Oppenheimer breakdown in the mass-scaling of these parameters to within our experimental accuracy. χ_aa( ⁶⁷Zn) of ⁶⁷Zn ³²S is also determined.
