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

    The emission spectrum of a molecular beam of NaI has been measured following excitation by the 248 nm KrF line of an excimer laser. The fluorescence structure, and the lifetime (17±2 ns), indicate the presence of a bound upper state not previously characterized. We identify this state as...
