Dynamics of Photoisomerization

1982
There has recently been a good deal of theoretical [1–3] and experimental [4–7] interest in activated barrier crossing processes in liquids. The best known model is that of Kramers [8] who derived expressions for the escape of particles over a barrier in various limiting cases. Combining Kramers ideas with recent kinetic theory calculations [1–3] leads

Photoisomerization of bentazone

Tetrahedron Letters, 1989
Abstract Photolysis of bentazone 1 in non-polar solvents e.g. n-hexane yields the unexpected photoproduct 2 . On irradiation in methanol and in water 1-methylbentazone and anthranilic acid isopropylamide as a degradation product are observed.

Ergosterol Photoisomerization Reaction Scheme

Journal of Pharmaceutical Sciences, 1973
The kinetics of the various isomers formed at low temperature by UV irradiation of ergosterol were studied experimentally at the wavelength λ = 253.7 nm. The characteristics of the photostationary state were used to determine the isomer precursor of the toxisterols as well as the quantum transformation yields of one isomer into another.

Photoisomerization and Thermal Isomerization of Arylazoimidazoles

The Journal of Physical Chemistry A, 2007
Photoisomerization and thermal isomerization behaviors of an extensive series of arylazoimidazoles are investigated. Absorption spectra are characterized by a structured pipi* absorption band around 330-400 nm with a tail on the lower energy side extending to 500 nm corresponding to an npi* transition.

Photoisomerization in Proteorhodopsin mutant D97N

Photochemistry and Photobiology, 2006
The first steps of the photocycle of the D97N mutant of proteorhodopsin (PR) have been investigated by means of ultrafast transient absorption spectroscopy. A comparison with the primary dynamics of native PR and D85N mutant of bacteriorhodopsin is given.
