Gutsche, G.Lawrance, W.Staker, W.King, K.2007-02-202007-02-201995The Journal of physical chemistry, 1995; 99(31):11867-118740022-36541541-5740http://hdl.handle.net/2440/874The technique of laser flash photolysis/laser absorption has been used to obtain absolute removal rate constants for singlet methylene, ¹CH<inf>2</inf> (ã ¹A<inf>1</inf>), with various oxygen-containing organic species. Removal rate constants for some 27 alcohols, ethers, ketones, aldehydes, carboxylic acids, and esters are reported for the first time. The removal rate constants for H<inf>2</inf>O and CH<inf>3</inf>OH have been remeasured and found to be in excellent agreement with values determined by other researchers. Improved removal rate constants for C<inf>2</inf>H<inf>5</inf>OH, n-C<inf>3</inf>H<inf>7</inf>OH, CH<inf>3</inf>OCH<inf>3</inf>, CH<inf>3</inf>CHO, CH<inf>3</inf>COCH<inf>3</inf>, CH<inf>3</inf>COOH, HCOOCH<inf>3</inf>, and CH<inf>3</inf>OCOOCH<inf>3</inf> are also presented. In all cases the removal rate constants are large, indicating that reaction is the dominant process leading to loss of ¹CH<inf>2</inf>. Comparisons are drawn between the reactivities of the various functional groups and between them and their hydrocarbon analogues. Because of the large data base provided by these measurements, mechanistic information can be inferred in a number of instances. © 1995 American Chemical Society.enJournal article003000307010.1021/j100031a013A1995RM901000132-s2.0-000047954967076King, K.
