摘要：

New high resolution polarization data have been obtained for the A-X band system of Li-6,7(2) , and new Fourier transform data for the homonuclear lithium dimers. They are combined with earlier data for Li-6,6(2) and Li-7,7(2) in the first systematic combined-isotopomer analysis of data for Li-2 . This analysis of 8445 rovibrational transitions yields an improved and internally consistent set of molecular constant for the three Li-2 isotopomers, and determines the electronic isotope shift and leading vibrational and rotational Born-Oppenheimer breakdown correction terms for both electronic states.
