Studying the photophysical dynamics of dG‐containing oligonucleotides by time‐resolved IR spectroscopy showed transient absorption changes pointing to excitation decay and vibrational cooling within a few picoseconds. On the 10‐500 picosecond time range transient charge‐transfer states were identified which are efficiently formed in these oligomers. The known reactivity and the high formation yield make charge‐transfer states important promoters for secondary reactions in DNA.

含鸟苷短 DNA 寡核苷酸中紫外线诱导的电荷转移状态。
通过时间分辨红外光谱研究含 dG 寡核苷酸的光物理动力学表明,瞬态吸收变化表明几皮秒内的激发衰减和振动冷却。在 10-500 皮秒时间范围内,确定了在这些低聚物中有效形成的瞬态电荷转移态。已知的反应性和高形成产率使得电荷转移态成为 DNA 二次反应的重要促进剂。
