We have studied fundamental aspects of photo-induced dissociation kinetics and dynamics in several phenyl halides. By combining femtosecond pump-probe measurements with ab initio calculations we are able to account for several observations. In mixed

The potential energy surfaces of the first excited triplet state of some ruthenium polypyridyl complexes were investigated by means of density functional theory. Focus was placed on the interaction between the geometrical changes accompanying the pho

The mechanism employed by DNA photolyase to repair 6-4 photoproducts in UV-damaged DNA is explored by means of quantum chemical calculations. Considering the repair of both oxetane and azetidine lesions, it is demonstrated that reduction as well as o

The C–Br photo-fragmentation of bromo-3,5-difluorobenzene (Br-3,5-diFBz) has been investigated using ab initio methods. A reaction coordinate combining a carbon–bromine bond stretch and a bromine out-of-plane bending on the S 1 surface has been f

The photoactivation of the plant photoreceptor phytochrome is governed by a red-light-induced C15- Z → C15- E isomerization of the tetrapyrrolic chromophore phytochromobilin. From the viewpoint of experimental studies, ambiguity prevails as to whet

Quantum chemical calculations aimed at identifying the factors controlling the acidity of phytochromobilin, the tetrapyrrole chromophore of the plant photoreceptor phytochrome, are reported. Phytochrome is converted from an inactive (Pr) to an active

The conversion of the plant photoreceptor phytochrome from an inactive (Pr) to an active form (Pfr) is accomplished by a red-light induced Z --E photoisomerization of its phytochromobilin chromophore. In recent years, the question whether the photoac
