摘要

用时间分辨率为5ps的激发光谱和探针束光谱研究了异辛烷中2,2′-联吡啶-3,3′-二醇(BP(OH)2)在紫外激发后的双质子转移。测定了主激发物质和互变异构体的激发态质子转移速率和激发态吸收带消光系数。

Picosecond Studies of Intramolecular Double Proton Transfer by Excite- and Probe-Technique

The double proton transfer of 2,2'-bipyridyl-3,3'-diol (BP(OH)2) in isooctane after UV excitation has been studied by excite and probe beam spectroscopy with a time resolution of 5 ps. Estimates for the excited state proton transfer rate as well as for the extinction coefficients of the excited state absorption bands of the primarily excited species and of the tautomer have been determined.
