✦ Synopsis

The sub-Doppler analysis of the ( A 1 ⌺ ϩ -X 1 ⌺ ϩ ) system is performed for 6 LiH and 7 LiH by crossing an effusive beam of LiH by a cw tunable laser beam in the near UV; 384 lines are measured between 357 and 385 nm and assigned to 6 LiH and 7 LiH with an accuracy of 5 ϫ 10 Ϫ3 cm Ϫ1 . Accurate Dunham coefficients and their mass-dependent corrections are deduced for the A 1 ⌺ ϩ electronic state of both isotopomers from the combination of previously published data and these new ones.

We report here new and more accurate molecular constants from sub-Doppler polarization spectroscopy of the A1Sigma+u-X1Sigma+g system of 6Li2 using single mode cw dye lasers. These new constants cover the range of vibrational levels from v" = 0-8 in the ground state and v' = 0-24 in the excited stat
