采用激光光解产生苯甲基,光致电离四极质谱技术测得苯甲基氧化反应的速率常数为(0.94±0.07)×10~(-12)/个·s,运用 ACM 统计速率理论计算得到一致结果。该结果进一步验证了过去的报导值,但都与 Bayes 经验规律有较大偏差,本文认为动力学质量效应是导致该偏差的重要原因之一。
The rate constant of benzyl oxidation was (0.94 ± 0.07) × 10 ~ (-12) / s · s, which was measured by laser photolysis of benzyl and photoionization quadrupole mass spectrometry. The ACM statistical rate theory was used to calculate Get a consistent result. This result further verifies the reported values in the past, but all of them have large deviations from the Bayes empirical rule. In this paper, we consider that the kinetic quality effect is one of the important causes of this deviation.
