摘要：

The pressure dependence of the OH + C2H4 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 to 361 Torr. 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 prereaction complex on the OH + C2H4 potential energy surface. The influence of this complex on the OH + C2H4 kinetics has been investigated using one-dimensional master equation analyses of the current and previous experimental measurements.
