Abstract
The polarisation labelling spectroscopy technique was applied to study the C X band system in potassium dimer. About 1100 new rotationally resolved molecular lines were measured in the ~cm spectral range. Perturbations of the lowest vibrational levels of the C state were localised and their origin discussed. A set of Dunham coefficients was deduced to fit the unperturbed levels of the C state with and and the potential energy curve of the state was constructed.
