## Abstract The present study of the cyclooctatetraene potential energy surface shows the presence of a bifurcation (valley ridge inflection point) in the intrinsic reaction coordinate path between the two transition states of D~8h~ and D~4h~ symmetries. This result is of capital importance for the
