The reaction dynamics of methylene radical CH2(X3B1) with N2O was investigated by Time-Resolved Fourier Transform Infrared Spectroscopy(TR-FTIRS). Pure CH2(X3B1) radicalwas produced via laser photolysis of ketene at 351 nm. Nascent viabrationally excited products CO, NO and HCN were observed. Some reaction pathways which may lead to these products were proposed and a possible reaction mechanism was outlined.

Key words: C2H, N2O, Reaction dynamics, TR-FTIRS
