Using sub‐picosecond CARS experiment we observed direct photolysis of liquid nitromethane after pulse excitation at 299 nm. We measured the dynamics behavior under excitation of three main ground state Raman lines: the ν (CN) mode at 917 cm−1, the νs(NO2) and δs(CH3) modes near 1400 cm−1 and the νs(CH3) mode at 2968 cm−1. From the evolution of these modes we deduced that the excited state disappears with a lifetime of 1.1±0.3 ps and we measured a photolysis quantum yield at 299 nm of 24%±5… CONTINUE READING
