中文摘要 AI 辅助

针对电荷转移中的手性诱导自旋选择性(CISS)已提出多种模型,但很少与实验直接对比,这对其验证和该领域未来发展至关重要。本研究通过计算相关电子顺磁共振(EPR)光谱,探究与不同微观模型相关的广泛自由基对态,这可明确不同自由基对态的独特特征、研究其实验可及性,并确定验证所提微观模型的条件。

英文摘要

Several models for chirality-induced spin selectivity (CISS) in charge transfer have been proposed, but rarely compared directly with experiments. This step is essential for their validation and future progress of the field. Here we investigate a broad class of radical pair states associated with different microscopic models by computing the related electron-paramagnetic resonance spectra. This allows us to evidence peculiar signatures of different radical pair states, to study their experimental accessibility and identify conditions to verify proposed microscopic models.
