摘要: A newly constructed single‐frequency, autoscan laser spectrometer operating in the ultraviolet combination with a collimated molecular beam has been used to obtain high resolution fluorescence excitation spectrum region 30 850–31 400 cm−1. Eight hundred and seventy five rotational lines of 7Li2 C 1Πu(v’=2–8)–X 1Σ+g 6Li7Li C 1Π(v’=2–4)–X 1Σ+ transitions are assigned. The constants C 1Πu state determined potential curve is using Rydberg–Klein–Rees (RKR) method. By comparing calculated Franck–Condon factors line intensities dispersed spectrum, we determine dependence electric dipole transition moment on internuclear distance.
