摘要: 在恒定、线性的梯度磁场存在下,用时间分辨ESR对某些典型体系在脉冲激光作用下产生的瞬态自由基的化学诱导动态电子极化信号进行了研究,发现用此方法可以获得它们的空间分辨及空间-时间分辨的2D-CIDEP信号.

Abstract: The CIDEP of transient radicals produced by pulsed laser irradiation in some typical systems in the presence of constant-linear gradient magnetic field have been investigated by time-resolved ESR method. It is found that the space-resolved and space-time-resolved two-dimensional CIDEP of the studied systems could be obtained respectively with the aid of time-resolved ESR and ESI techniques.
