| The polarisation labelling spectroscopy method is applied to study the C1&Sigmap;+ <-- X^1 &Sigmap;+ band system of the KLi molecule. Rotationally resolved polarisation spectra are observed in the spectral range of 17150--20350 cm-1. A set of Dunham coefficients describes the C1&Sigmap;+ state to 95% of its potential well depth, and the potential curve is constructed by the Rydberg--Klein--Rees procedure. The molecular parameters deduced from this work are compared with theoretical calculations. |
