Pulse initiation of photoreactions in a combination to pulse technics of registration of spectra of a nuclear magnetic resonance allows to register astable intermediate products and to investigate kinetics their destructions. In given clause experimental installation for carrying out pulse photolysis and a technique of measurement kinetics an astable intermediate product is described. Experiments were spent on spectrometer TESLA-587А. Changing time of a delay of a radio-frequency impulse of a spectrometer, concerning flash of a lamp and registering a spectrum of a nuclear magnetic resonance it is possible to receive dependence of amplitude of signals of separate lines of a spectrum on time of a delay. By means of the specified way of registration of spectra of a nuclear magnetic resonance, at approbation of the device, time of a life of an astable product has been measured. Studying of mechanisms and kinetics photolysis modeling connections has allowed not only to fulfill a technique of experiment, but also to add an information available in the literature on mechanisms photo dissociation a products
