Molecular beams have been widely used for experiments of gas-surface interactions. Most fundamental properties such as translational energy and momentum of molecular beam have been analyzed very well, while 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 technique, which is able to measure molecular internal energy such as rotational 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 REMPI, and analyzed the rotational energy distribution of the nitrogen molecules in the molecular beam.
