摘要：

Kinetics of the colouring and bleaching reactions in polycrystalline 1-methyl-2,4,4,6-tetraphenyl-1,4-dihydropyridine embedded in KBr matrices were studied employing a non-isothermal technique. The results reported in the paper supplement those reported earlier, pointing to the existence of two parallel processes responsible for the photochromic activity of the material. Results of quantum-chemical calculations and spectroscopic measurements allow us to suggest possible reaction paths.
