The results of two separate studies of the complex between NO and N2 are reported. The (1+1) REMPI spectrum of the ? transition of the complex between NO and N2 is presented of improved quality over that reported previously, and the appearance of the spectrum is discussed. The results of high-level ab initio calculations [RCCSD(T)/aug-cc-pVQZ//QCISD/6-311+G(2d)] on the ?2? state are also reported. The indications are that the NO moiety is more freely rotating in the complex than is N2, and that a wide angular space is sampled in the zero-point energy level. The appearance of the REMPI spectrum suggests that the ?2S+ state is (close to) linear, and RCCSD(T)//QCISD calculations on the state, using Rydberg-function-augmented basis sets, suggest that the lowest energy linear isomer is the ON·N2 linear orientation. It is clear, however, that the understanding of this complex, and its spectroscopy, is far from complete, and will be challenging. © 2000 American Institute of Physics.
