Rate constants for the reactions of 1- and 2-hydroxyethyl radicals with O2 and NO were measured at room temperature by laser flash photolysis-photoionization mass spectrometry method. The results are as follows (in units of cm3 molecule-1 s-1): CH3CHOH+O2 ((2.8 ± 0.2) × 10-11); CH3CHOH+NO ((2.4±0.6)× 10-11); CH2CH2OH + O2 ((3.0± 0.4)x 10-12); CH2CH2OH+NO ((2.6 ±0.7)× 10-11). The reaction of 1-hydroxyethyl radical with O2 was found to be approximately one order of magnitude faster than 2-hydroxyethyl radical. The reaction mechanism seems to be different for the two hydroxyethyl radicals.
