dc.description.abstract | Dynamic shaping of the adiabatic tunneling barrier in the S-H bond extension coordinate of several ortho-substituted thiophenols has been found to be mediated by low-frequency out-of-plane vibrational modes, which are parallel to the coupling vector of the branching plane comprising the conical intersection. The S-H predissociation tunneling rate (k) measured when exciting to the S i zero-point level of 2-methoxythiophenol (44 ps)(-1) increases abruptly, to k approximate to (22 ps)(-1), at the energy corresponding to excitation of the 152 cm(-1) out-of-plane vibrational mode and then falls back to k approximate to (40 ps)(-1) when the in-plane mode is excited at 282 cm(-1). Similar resonance-like peaks in plots of S-1 tunneling rate versus internal energy are observed when exciting the corresponding low-frequency out-of-plane modes in the S-1 states of 2-fluorothiophenol and 2-chlorothiophenol. This experiment provides clear-cut evidence for dynamical "shaping" of the lower-lying adiabatic potential energy surfaces by the higher-lying conical intersection seam, which dictates the multidimensional tunneling dynamics. | - |
