A variational approach for calculating Franck-Condon factors including mode-mode anharmonic coupling
Photoassociation inside an optical dipole trap: absolute rate coefficients and Franck–Condon factors
A full-dimensional Franck-Condon calculation has been applied to the à (1)Au-X̃ 1Σg+ transition in acetylene in the harmonic normal mode basis. Details of the calculation are discussed in Part I of this series. To our knowledge, this is the first full-dimensional Franck-Condon calculation on a tetra-atomic molecule undergoing a linear-to-bent geometry change. In the current work, the vibrational...
The Condon approximation is widely applied in molecular and condensed matter spectroscopy and states that electronic transition dipoles are independent of nuclear positions. This approximation is related to the Franck-Condon principle, which in its simplest form holds that electronic transitions are instantaneous on the time scale of nuclear motion. The Condon approximation leads to a long-held...
The dependence of the rate constant for electron transfer on energy can be systematically studied by measuring kinetics in an applied electric field. General relationships are developed between observed electric-field-modulated kinetics and theoretical expressions for the electron transfer rate constant, including both the energy dependence of the nuclear (Franck-Condon) and superexchange elect...
Broadband ultraviolet absorption spectroscopy has been used to determine CF(2) densities in a plasma etch reactor used for industrial wafer processing, using the CF(2) A (1)B(1)<--X (1)A(1) absorption spectrum. Attempts to fit the experimental spectra using previously published Franck-Condon factors gave poor results, and values for the higher vibrational levels of the A state [(0,v(2),0), with...
