The paper presents the results of experimental studies of the effect of selective photo-excitation on the diffusion of molecules of organic dyes Rhodamine 6G and Oxazine 1 perchlorate through silica gel. The experimental results are compared with the theoretical model presented in our previous work, which describes a decrease in the diffusion rate of molecules being excited by laser radiation and brought into triplet state. The experimental data obtained in the course of the present study are in qualitative agreement with the model just mentioned. It was shown that after selective photo-excitation of Rhodamine 6G molecules and their transition into triplet state, the diffusion rate decreased by 40% compared with molecules in the ground state.

通过选择性光激发分离有机染料分子

本文介绍了选择性光激发对有机染料罗丹明6G和高嗪酸恶嗪1分子通过硅胶扩散的影响的实验研究结果。将实验结果与我们先前工作中提出的理论模型进行了比较，该模型描述了被激光辐射激发并进入三重态的分子的扩散速率的降低。在本研究过程中获得的实验数据与刚才提到的模型在质量上是一致的。结果表明，若丹明6G分子被选择性光激发并转变为三重态后，与基态分子相比，扩散速率降低了40％。
