The reaction of methylene radicals in their 3 B1 electronic ground state with molecular NO was studied. Pure CH2(X 3 B1 ) radicals were produced by UV photolysis of ketene at 351 nm. The products were measured by Time-Resolved Fourier Transform Infrared (TR-FTIR) spectrometer. CO.OH .NH2 and HOCN or its isomer HNCO were found as primary products and several possible channels of this reaction were suggested.

Key words: CH2(X3B1), State-specific reaction, TR-FTIR;NO
