Duschinsky effect
WebSep 10, 2013 · The effect of excitation on the vibrational spectra of C337 was analyzed. A single C337 molecule and its five different hydration complexes with strongly bound water molecules have been analyzed. WebThe assumption that the difference in composition, in terms of symmetry coordinates, between the normal vibrational motions of the ground and first excited state (Duschinsky effect) can be neglected in the Herzberg-Teller theory of absorption and fluorescence vibronic intensities is examined.
