Transition stati theory is tested against accurate rate constants for the colLLaear H + Ef P reaction oa a realistic potential energy surface. For this reaction the theory is fafrfy accurate at higti'temperatures but is very inaccurate at low temperatures.
The generalized Langevin equations are presented by considering such microscopic motions of molecules described by the microscopic Hamiltonian whose potential function is quadratic and internal degree of freedom is multidimensional. Considering the long time behavior of the reactive mode, the Grote-
