The B 1Π-X 1Σ+ band system of the 39K7Li molecule was investigated by Doppler-free polarizationon spectroscopy in a heat-pipe oven. Precise molecular constants for levels v=0-3 in the ground X 1Σ+ state and levels v=0-2 in the excited B 1Π state were determined. The e-parity components in all three vibrational levels of the B state were found to be subject to rotational perturbations, assigned to interaction with the C 1Σ+ state. The deperturbation analysis provided preliminary constants of the perturbing C state and values of the coupling matrix elements.
