摘要: 用高时间分辨ESR谱仪实验给出了光解对苯醌产生的苯半醌自由基的CIDEP发射谱.用三重态机理,同时考虑了自由基对机理的影响,从理论上分析了极化强度,计算出了增强因子V(Ⅰ)=-0.66,V(R)=0.2,一级反应速率k1,A=0.05/μs,二级反应速率β=0.02/μs,横向和纵向弛豫时间T1T2=2.3μs.

Abstract: The CIDEP emission spectrom of P-benzosemiquinome radocal by photolysing P-benzoquinome was obtained experimentally with the highly time resolved ESR spectrometer.Using TM and RPM mechamisms,we invesigated the polarization of the radical and clculated the cahamcements V(I)=-0.66.and V(R)=0.2,the first order mention rate k1,A=0.05/μs,the second order spin selective reaction mate β=0.02/μs,and the relaxation time T1=T2=2.3μs.
