Impute photoconductivity of pyridine solutions of chlorophyll a and pheophytin a in the presence of phenylhydrasin was studied, as well as that of tetraphenylporphin, zinc-tetraphenylporphin, mezoporphyrin, zinc-mezoporphyrin, and palladium-mezoporphyrin in the presence of hydrasin hydrate depending on flash intensity and temperature (20--30 degrees C). The lifetimes of anion-radicals and monoprotonated dianions of the studied pigments were estimated, as well as activation energies of some intermediate stages of photoreduction. From the data obtained the ratio between the constant of the death rate of anion-radicals and the total mobility of negative and positive ion-radical was found.
