| 摘 要： | 在理论上研究了顺磁性粒子体系的圆偏振激光诱导的ＥＳＲ谱频移效应。给出磁场中分子反对称极化率的公式，并以［ＩｒＢｒ６］＾２－离子为例讨论了吸收带半高宽的影响。计算了［ＩｒＢｒ６］＾２－的ＥＳＲ谱在圆偏振激光作用下的频移。结果发现：在光学共振区附近，ＥＳＲ频移可达１ＭＨｚ的量级，与钠原子体系结果类似。

| Abstract: | This paper studies theoretically the effect of circularly polarized laser on ESR spectra in a spin specie system. The antisymmetric polarizability and the laser-induced ESR shift (Δv -- Δv+) of the complex IrBr6]2- were calculated. The influence of the width г of the absorption line on the ESR shift was discussed. The results show that the ESR shift can be as large as 1MHz order of magnitude at a frequency near optical absorption, which is similar to that of the sodium atom. |
