Terenetska I. Spectroscopy and laser photochemistry of provitamin D

The object is photosynthesis of previtamin D; the aims to determine the influence of laser radiation on the photoreaction kinetics for the photoreaction channels control; the method is UV absorption spectroscopy; the new approach lies in determination of the new wavelength and intensity effects on the photoreaction kinetics and the photoproducts yield, and the effects of various reaction media on the conformational equilibrium of previtamin D and its cis-trans isomerization; the main results include original spectrophotometric analysis of the multicomponent mixture of provitamin D photoisomers, the new method of solar biologically active UV radiation monitoring and personal UV biodosimeter; the fields are molecular spectroscopy, laser biophysics, photobiology.
