质子化芳烃分子的电子激发态：质子化芴
Electronic excited state of protonated aromatic molecules: protonated Fluorene
摘要：
质子化芴的光碎裂光谱在可见光区被记录下来，与中性芴的第一激发态吸收相比，有很大的红移。光谱显示了两个不同的振动级数，分离0.19 eV，被分配给两个异构体的吸收。在质子化的线性多环芳烃，与从头计算的比较表明，红移是由于激发态的电荷转移字符。
英文摘要：
The photo-fragmentation spectrum of protonated fluorene has been recorded in the visible spectral region, largely red shifted as compared to the first excited state absorption of neutral fluorene. The spectrum shows two different vibrational progressions, separated by 0.19 eV that are assigned to the absorption of two isomers. As in protonated linear PAHs, comparison with ab-initio calculations indicates that the red shift is due to the charge transfer character of the excited state.
