Abstract:
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 7 Li 7 Li species, accurate spectroscopic studies of the B 1 Π u ‐X 1 Σ g + 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 1 π u state. They led to the full description of the B state potential, including its barrier. For 6 Li 7 Li species, weak but non‐negligible dissociation rates in the B 1 Π u state were observed, measured and interpreted assuming that an electronic coupling between the B 1 Π u and 1 1 Π g states takes place through an ungerade ‐ gerade symmetry breaking. For LiH species, the A 1 Σ + ‐X 1 Σ + 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.
