β¦ Synopsis
The CHsOs radical was generated by pulsed laser photolysis and was detected directly by photoionization mass spectrometry. The radical was photoionized by the Ar resonance lines ( 11.62 and 11.83 eV) and detected as the parent ion, CHsO: . Reactions of CH302 and CDs02 with NO were studied by time-resolved measurements of the radical ion signals. The following rate constants were obtained at 298fS K: k(CHs02+NO)=(11.2f 1.4)x 10-t* cm' molecule-' s-' and k(CD302+NO)= ( 10.9 f 1.3) x 10-t* cm3 molecule-' s-'. The values are 50% larger than those previously reported.
