低压下,高频或微波放电能够使气相有机化合物发生化学反应的事实早为人们所注意。但究其反应机理是否是通过自由基进行的?过去一般是通过分析反应的最终产物来推测的,并无直接证明。即是使用ESR研究它们,由于气相自由基中旋转角动量和电子轨道
The fact that low-pressure, high-frequency or microwave discharges can chemically react gas-phase organic compounds has long been noticed. But whether its reaction mechanism is carried out by free radicals? The past is generally speculated by the analysis of the final product of the reaction, there is no direct proof. That is, they are studied using ESR due to the angular momentum and electron orbitals in the gas-phase free radicals
