Photodissociation of bulk nitrobenzene at 250, 266, and 280Â nm using a picosecond laser

- We studied photodissociation of nitrobenzene using a picosecond laser at 250, 266, and 280 nm photolysis wavelengths.
- We monitored the evolution of NO photofragments as a function of time delay between 250 nm-photolysis and excitation laser pulses.
- A bimodal rotational distribution was observed; the distribution profile depends on the photolysis wavelength.
- Vibrational populations distribution for v″ = 0, 1, 2 were determined for NO photofragments.
