A novel laser spectroscopic method with a molecular beam is successfully demonstrated. This technique is widely applicable for studies of collisional relaxation on a variety of molecular transitions, even when untunable infrared molecular lasers are used. The effect of collision-induced transitions between the vibration--rotation levels of NH/sub 3/ are investigated by infrared--infrared double resonance. It is found that the rate of excitation energy transfer is closely related to the molecular energy level structure.
