The perturbation in the 4-0 band of the SnO A Ⅱ-X ∑+ electronic transition
In this paper, the measurement of the laser induced fluorescence (LIF) of SnO A II- has been made. The rotational structures of the spectra were fully assigned both for Sn118O and for Sn120O. We report the effect of isotope shift on the perturbation center for the first time. The characteristic of perturbation is also analysed by Kovacs method.
