Abstract

Sub-Doppler optical-optical double resonance polarization spectroscopy is applied to study highly excited states of NaK molecule. New three1Δ states and two1Σ+ states are identified and the molecular constants are determined. Transitions from rotationally energy transferred levels are observed, and this indicates the strong conservation ofM J through the energy transfer by collisions. The linewidths are found to increase with ΔJ, and this implies that the velocity vector approaches to the thermal distribution as ΔJ increases.
