Wentzel-Kramers-Brillouin theory

Still another method, namely use of the WKB (Wentzel-Kramers-Brillouin) theory, has been suggested by Englman and Ranfagni (1980) for use with multidimensional or complex energy surfaces. [Pg.51]

In the approximation of the Wentzel-Kramers-Brillouin method, we take fi = k(l)unf a) from the Landau theory on the hydrodynamic instability of the plane flame. The relative change in the disturbance because of the stretch-effect is equal to that in the tangential velocity component... [Pg.472]

Per-Olov Lowdin had a long and lasting interest in the analytical methods of quantum mechanics and my tribute to his legacy involves an application of the Wentzel-Kramers-Brillouin (WKB) asymptotic approximation method. It was the subject of a contribution(l) by Lowdin to the Solid State and Molecular Theory Group created by John C. Slater at the Massachusetts Institute of Technology. [Pg.88]

The effects of X7 may be treated using ordinary non-degenerate perturbation theory or, as in Dunham s original work, by means of the Wentzel-Kramers-Brillouin method... [Pg.65]

This is supported by computed rate constants with tunneling contributions using the semiclassical Wentzel-Kramers-Brillouin (WKB) theory. The WKB procedure requires a carefully described intrinsic reaction path, and... [Pg.349]
