A new type of reaction pathway which involves a nontotally symmetric trifurcation was found and investigated for a typical S(N)2-type reaction, NC-+CH3X NCCH3+X- (X=F, Cl). A nontotally symmetric valley-ridge inflection (VRI) point was located along the C-3v reaction path. For X=F, the minimum energy path (MEP) starting from the transition state (TS) leads to a second-order saddle point with C-3v symmetry, which connects three product minima of C-s symmetry. For X=Cl, four product minima have been observed, of which three belong to C-s symmetry and one to C-3v symmetry. The branching path from the VRI point to the lower symmetry minima was determined by a linear interpolation technique. The branching mechanism is discussed based on the reaction path curvature and net atomic charges, and the possibility of a nonotally symmetric n-furcation is discussed.
