Sažetak
The resonance Raman effect is examined in the case of vibrations
which are governed by a double well potential. It is shown
that in such a case the intensity of a resonance Raman line depends
on three factors: the relative populations of the two wells in the .
ground state and in the resonating electronic excited state and the
displacement of the potential minima between the ground state
and the excited state. Depending on the shapes of the potentials
in the two states, the ground state populations might become
unimportant as a factor determining intensities and the only
observed Raman line might be due to the less populated well. It
is suggested that such a situation is likely to exist for the proton
bridge of the chromophore of visual pigments and bacteriorhodopsin,
the Schiff bases of 11-cis and all-trans retinals respectively.
This raises the question if resonance Raman spectra alone
are capable of giving evidence of the extent of protonation of the
chromophore in the ground state.
