本文介绍了4-二甲氨基苯甲腈(DMABN)双荧光的分子内电荷转移(ICT)反应的新的实验和理论结果，表明完全扭曲ICT(TICT)态是产生时间分辨的瞬时吸收光谱的原因，而荧光ICT态则是独特的部分扭曲ICT(PTICT)结构。
In this contribution we present new experimental and theoretical results for the intramolecular charge transfer (ICT) reaction underlying the dual fluorescence of 4-(dimethylamino) benzonitrile ( DMABN), which indicate that the fully twisted ICT (TICT) state is responsible for the time-resolved transient absorption spectrum while a distinct partially twisted ICT (pTICT) structure is suggested for the fluorescent ICT state.
