The report describes a ruby laser nanosecond flash photolysis system which was set up in the Explosives Division, Feltman Research Laboratory, Picatinny Arsenal to study the chemical reactivity of electronically excited states of aromatic nitrocompounds. The system is capable of recording absorption spectra of transient species with half-lives in the range of 20 nanoseconds to 1 millisecond. Kinetic data pertaining to the lifetime of electronically excited states can be recorded by following the transient absorption as a function of time. Preliminary data on the spectroscopic and kinetic behavior of 1,4-dinitronaphthalene triplet excited state were obtained with the equipment described in the report. Author
