Title: Kinetic Study of the OH + Ethylene Reaction using Frequency Modulated Laser Absorption Spectroscopy

The pressure dependence of the OH + C 2H 4 addition reaction has been investigated using frequency modulated laser absorption spectroscopy to monitor OH kinetics. Bimolecular rate coefficients for the title reaction are reported in argon bath gas at room temperature and total pressures ranging from 2–361Torr. The pressure dependent rate coefficients measured here agree well with the majority of published kinetic studies under similar conditions. Previous high-level ab initio calculations have identified a pre-reaction complex on the OH + C 2H 4 potential energy surface. In conclusion, the influence of this complex on the OH + C 2H 4 kinetics has been investigated using one-dimensional master equation analyses of the current and previous experimental measurements
