| Abstract
| - Kinetics studies of the OH-initiated oxidation of 2-butyne, propyne, and acetylene were conducted at 100Torr and 298 K using turbulent flow chemical ionization mass spectrometry. The major oxidation productswere identified, and with the aid of supporting electronic structure thermodynamics calculations, a generalOH-initiated oxidation mechanism for the alkynes is proposed. The major product branching ratio and theproduct-forming rate constants for the 2-butyne-OH adduct + O2 reaction were experimentally determined aswell. The atmospheric implications of the chemical oxidation mechanism and kinetics results are discussed.
