✦ Synopsis

The reaction of CH2, particularly the ground electronic state triplet CH2 [l], with 0 2 is known to be very fast. The effectiveness of the reactions involving both singlet (lCH2) and triplet (3CH2) methylene was most dramatically demonstrated by the drastic effects of O2 on CO laser emissions in both O(3P) -CzH2 [2] and CH,CO photodissociation [3] laser systems. Although the observed effects were apparently opposite in these two cases, they were believed to have resulted from the rapid occurrence of the CHZ + 0 2 reaction via presumably the following mechanism [a] : C H ~ + 0, -L . CH,OO. or CH, -HCOOH~
