For the development of high-vacuum technology and micro/nano-devices, interactions of gas molecules and solid surfaces must be analyzed. Molecular beams have been widely used for experiments of gas-surface interactions, but there are very few reports analyzing the internal energy (e.g. rotational energy) of diatomic or polyatomic molecular beams experimentally. Resonantly-enhanced multiphoton ionization (REMPI) method is a spectroscopic measurement technique, which is able to measure molecular internal energy. Moreover, REMPI has very high detection sensitivity, and it can be applied to analyses of very low density gas flows. In this study, we have tried to detect a nitrogen molecular beam by 2R+2 N_2-REMPI, and analyzed the rotational energy distribution of nitrogen molecules in the molecular beam.
