摘要: Abstract Polarization labelling spectroscopy of the B1Π←X1Σ+ and C1Σ+←X1Σ+ band systems in KLi reveals strong mutual perturbation B C states. We show that both excited states can be described a model comprising numerical IPA potentials for unperturbed only 3 parameters to describe their interaction. Our approach allows identify many previously unassigned spectral lines having significant deviation from “regular” positions.
