摘要：
Numerical calculations show that four modern potential energy surfaces for N-2-He all support 18 bound intermolecular states for the homonuclear isotopologues N-14,14(2)-He-4 and N-15,15(2)-He-4, and 12 (or 13, for one surface) truly bound states for N-14,15(2)-He. This contradicts a recent statement [Patel , J. Chem. Phys. 119, 909 (2003)] that one of these surfaces supports no bound states, and it yields predictions for 27 allowed pure rotational transitions among the truly bound states of the homonuclear isotopologues of this complex.
