✦ Synopsis

We report the first observation of the Liz diffuse band in the region of 420 nm which is the analog of the diffuse bands in other alkali diier spectra, for example. at 436.5 and 575 nm for the sodium and potassium cases, respectively_ The observed diffuse band appears to arise from the 2 311g-l 'Xi transition where the upper state corresponds to the 2p + 2p asymptote, and is subjected to the interesting configuration interaction with the potential curve of the ionic mollxule LiC3PJ + Li?rSJ with the same symmetry_ The or&gin of the 420 run band is interpreted in terms of theoretical cakuJatior.s of various Lia potential difference curves.

## Abstract Complex spectra of the KRb 420 nm system are analyzed by mass‐resolved resonance enhanced two‐photon ionization in a cold molecular beam. Vibronic structures of three singlet–singlet (4 ^1^Π, 7 ^1^Σ^+^, and 5 ^1^Π←__X__ ^1^Σ^+^) transitions were identified for the first time. By compari
