自旋捕捉技术与ESR相结合,为检测反应过程中产生的自由基活泼中间体提供一个方便且有效的方法。近年来,国内外研究工作者利用这一方法,对固相,液相和气相中产生的活泼自由基已进行了广泛的研究。特别是对二苯酮与质子给体如:醇、胺、 The combination of spin-capture technology and ESR provides a convenient and efficient method for detecting reactive free-radically active intermediates during the reaction. In recent years, researchers at home and abroad have used this method to conduct extensive research on active free radicals generated in solid phase, liquid phase and gas phase. In particular, benzophenone and proton donors such as: alcohols, amines,
