abstract = {The short-time photodynamics (2 ps) of formamide embedded
into an Ar matrix starting from the low-lying singlet
excited S(1) (n(0)π*) and S(2) (ππ*) states were explored
using a nonadiabatic photodynamics QM/MM approach. The
interaction between formamide and the Ar matrix is taken
into account at the MM level by means of Lennard-Jones
potentials. This is the first example of exploring
photodissociation of formamide with full nonadiabatic
dynamics in a matrix and it nicely illustrates importance of
considering environmental effects on photodissociation
behavior of the peptide bond. It is shown that embedding of
the formamide molecule in the argon matrix has strong impact
on the outcome of the process. This is illustrated by
formation of the 1:1 complex between ammonia and CO and
prevention of full separation of the NH(2)˙ and HCO˙
subunits in the NH(2)˙ + HCO˙ radical pair. In addition,
the argon matrix strongly influences the lifetime of the
S(1) state, which increases by 211 fs relative to the gas
phase.},
