The photoisomerization of stilbene is an important model for the study of reaction dynamics
in the con-densed phase. It is also representative of cis/trans isomerization reactions, a class …

Polyphenylenevinylene PPV and its derivatives are widely studied as materials for organic
light emitting diodes. 1 The knowledge of the parameters which control the photophysical …

The photochemistry of stilbene is investigated using ab initio quantum chemistry with
complete active space self-consistent field (CASSCF) and multireference perturbation theory …

At first sight, the cis e trans photoisomerization of stilbene seems to be nothing but a simple
example of a fundamental photochemical process: twisting about the C= C double bond …

▪ Abstract The fundamental quantum mechanics, group theory, and spectroscopy of methyl
torsional structure accompanying electronic transitions is presented. The origin of barriers to …

The donor/acceptor (D/A) substituted π-conjugated organic molecules possess extremely
fast nonlinear optical (NLO) response time that is purely electronic in origin. This makes …

Information on the behavior of many molecules thought to undergoconformational
equilibration in the ground state is abundant in the scientific literature. As an example, the …

The electronic structure and spectroscopy of linear polyenes were reviewed by Hudson and
Kohler in 1974 and again in 1982.1'2 Although some parallels exist between the …

We report the detailed XMCQDPT2/cc-pVTZ study of trans–cis photoisomerization in one of
the core systems of both experimental and computational photochemistry the stilbene …
