摘要: The 7LiH D 1Σ+ excited electronic state has been observed for the first time by a pulsed optical–optical double resonance fluorescence depletion spectroscopic technique. Several rovibrational levels of A 1Σ+ and B 1Π states have used as intermediate states. Among 22 vibrational levels, 128 observed. spectral assignment is identified rotational structures term values comparison between derived constants with theoretical values. An ab initio adiabatic potential energy curve relevant D 1Σ+–A 1Σ+ D 1Σ+–B 1Π transition moment functions are presented. overall measure three different aspects, energetics, line shape, probability, strongly favors argument that vibronic approach better characterizing state.
