title: High resolution electronic spectroscopy of the A (2)Σ- - X (2)Π1/2 transition of PtN.
abstract: The (2,0) vibrational band of the A (2)Σ(-) - X (2)Π1/2 transition of platinum nitride, PtN, was recorded at Doppler-limited resolution using intracavity laser absorption spectroscopy (ILS) and at sub-Doppler resolution using molecular beam laser induced fluorescence (LIF) spectroscopy. Isotopologue structure for (194)PtN, (195)PtN, and (196)PtN, magnetic hyperfine splitting due to (195)Pt (I = ½), and nuclear quadrupole splitting due to (14)N (I = 1) were observed in the spectrum. Molecular constants for the ground and excited states are derived. The hyperfine interactions are used to illuminate the nature of the A (2)Σ(-) excited electronic state.
