The photochromtsm of 4-(2',4'-dmttrobenzyl)-pyndme was investgated by means of laser flash photolysis Two coloured tranaents were obserwd m the spectral ran\_ees of 390-430 nm and 510-590 nm us ethanol and acetonitrde. The first band (390-430 nm, hfetune = 100-500 ns) IS the absorptton band of the a
