Abstract
Fluorescence anisotropy decay kinetics of the pyrazoline derivatives h as been investigated in the toluene solvent and PMMA polymer films. Th e obtained data confirm a significant effect of the acceptor peculiari ties of a fragment lying in the third position of the pyrazoline heter ocycle on the molecular structure geometry. Rotation and relaxation of configuration times typical of the photoexcited molecules are obtaine d.
