Summary: | [Display omitted]
► The millimeter- and submillimeter-wave spectra of PtS were observed. ► Rotational transitions were recorded for four isotopomers in the X3Σ0- ground state. ► The spectroscopic constants were determined using a Hund’s case (c) Hamiltonian. ► The lower limit of 3Σ0--3Σ1- is estimated from a Hund’s case (a) analysis.
The millimeter- and submillimeter-wave spectra of PtS in the X3Σ0- state were observed by employing a source-modulated microwave spectrometer. The PtS radical was generated in a free space cell by using a dc glow plasma of H2S and Ar. Platinum atoms were supplied from a small piece of platinum sheet lining the inner surface of a stainless steel cathode by the sputtering reaction. Rotational transitions were recorded for four dominant isotopomers, 194PtS, 195PtS, 196PtS, and 198PtS in the X3Σ0- ground state, and the spectroscopic constants for each isotopomer were determined using a Hund’s case (c) Hamiltonian. The lower limit of the 3Σ0−-3Σ1− energy separation is estimated from a Hund’s case (a) analysis. |
