| Abstract: | We report a picosecond pump-probe study of the UV photolysis of gaseous dimethylnitramine. After photolysis by picosecond laser pulses at 266 nm, efficient monophotonic collision-free photodissociation occurs within 6 ps. NO2 fragments are formed in the ground electronic state and in a fluorescent excited state; the quantum yields for both of these channels are estimated. |
