abstract = {The nonadiabatic photodynamics of the
all-trans-2,4-pentadiene-iminium cation (protonated Schiff
base 3, PSB3) and the
all-trans-3-methyl-2,4-pentadiene-iminium cation (MePSB3)
were investigated in the gas phase and in polar (aqueous)
and nonpolar (n-hexane) solutions by means of surface
hopping using a multireference configuration-interaction
(MRCI) quantum mechanical/molecular mechanics (QM/MM) level.
Spectra, lifetimes for radiationless deactivation to the
ground state, and structural and electronic parameters are
compared. A strong influence of the polar solvent on the
location of the crossing seam, in particular in the bond
length alternation (BLA) coordinate, is found. Additionally,
inclusion of the polar solvent changes the orientation of
the intersection cone from sloped in the gas phase to
peaked, thus enhancing considerably its efficiency for
deactivation of the molecular system to the ground state.
These factors cause, especially for MePSB3, a substantial
decrease in the lifetime of the excited state despite the
steric inhibition by the solvent.},
