Rotational profiles in the excitation spectrum recorded for the B31(53P1)←X10+(51S0) transition in CdNe van der Waals complex

We report rotational profiles in the laser induced fluorescence excitation spectrum recorded for the B31(53P1)←X10+(51S0) transition in CdNe van der Waals complex. A method of analyzing the rotational structure of overlapping vibrational bands with isotopic spectral contributions is discussed. Rotational characteristics Bυ and Dυ for the υ′=0, 1, 2 and υ″=0 are reported.
