An actual crossing seam of two potential energy surfaces of thesamesymmetryrelevant to the charge transfer reaction H++NO(Xthinsp;2Pgr;)rarr;H(2S)+NO+(Xthinsp;1Sgr;+) is reported. This crossing seam occurs for generalCsgeometries. It represents the intersection of the 1,22Arsquo;potential energy surfaces which correlate asymptotically with H(2S)+NO+(Xthinsp;1Sgr;+) and H++NO(Xthinsp;2Pgr;), respectively. A portion of the seam is exoergic relative to the reactant channel, H++NO(Xthinsp;2Pgr;), asymptote. The present results complement a previous determination of twoallowedcrossing seams inCinfin;vsymmetry, and provide, for the first time, an example of a system for which both allowed and actual conical intersections exist. Since the actual crossing seam occurs for geometrical configurations quite distinct from the allowed crossing seams previously considered these results have important implications for the rotationalndash;vibrational energy distribution in the products of the charge exchange process.
