C-1 Sigma(+) state of (LiH)-Li-7
The (LiH)-Li-7 C-1 Sigma(+) excited electronic state has been observed for the first time by pulsed optical-optical double resonance fluorescence depletion spectroscopy. Several rovibrational levels of the A(1) Sigma(+) excited electronic state have been selected as the intermediate states. Among 10 vibrational states of the C-1 Sigma(+) electronic state 81 rovibrational levels have been observed. The spectral assignment is identified from the observed rotational structures, term values, and vibrational level spacings and from a comparison with recent accurate ab initio calculations of Boutalib and Gadea [J. Chem. Phys. 1992, 97, 1141].
