- 中文摘要: Deep insights into molecular structures and dynamics were obtained for lithium dimers and lithium hydrides by sub-Doppler spectroscopy combining molecular beams and cw tunable laser beams. For 7Li7Li species, accurate spectroscopic studies of the B 1Pu-X 1Sg+ system were carried out, with the measurement of hundreds of wave numbers and with the determination of dissociation rates due to tunneling through the potential barrier of the B 1Pu state. They led to the full description of the B state potential, including its barrier. For 6Li7Li species, weak but non-negligible dissociation rates in the B 1Pu state were observed, measured and interpreted assuming that an electronic coupling between the B 1Pu and 1 1Pg states takes place through an ungerade-gerade symmetry breaking. For LiH species, the A 1S+-X 1S+ system was revisited for both isotopomers. For this molecule, dynamical effects are predicted in highly-excited Rydberg states, that could be studied by use of similar sub-Doppler techniques.
