摘要：

The rotationally resolved absorption spectrum of LiAr due to the transition A(2) Pi <-- X(2) Sigma has been investigated by laser spectroscopy producing the molecules in a supersonic jet beam. Vibrational levels with upsilon = 0,...,3 and upsilon = 5,...,9 have been observed up to now for the X(2) Sigma and the A(2) Pi state, respectively. The X Sigma interaction potential has been determined by means of a quantum mechanical method using a Hartree-Fock dispersion function. For the well-depth and equilibrium distance of X Sigma we obtain D-e = 42.5(1.2) cm(-1), R(e) = 4.888(15) Angstrom. Our preliminary results for the A(2) Pi state are: D-e = 925(40) cm(-1), R(e) = 2.48(6) Angstrom.
