摘要：

The structure and energy of the NO-(3Σ- )⋯He(1S) system have been studied by means of the Moller-Plesset perturbation theory. The potential energy surface was found to be very flat and fairly isotropic, with three shallow minima. The global minimum was found for the collinear configuration N-O⋯He, RNO = 1.28 Å, ROHe = 3.25 Å, and De = 69 cm-1. For the same configuration we also studied the NO-(3Σ-)⋯Ar(1S) complex and found the well parameters ROAr = 3.25 Å and De = 509 cm-1, to be compared with the experimental estimate of De = 460 cm-1. In both systems the electron correlation contribution is very important and constitutes about half of the total interaction energy. © 1990 American Chemical Society.
