摘要: A photoinitiated intermolecular electron−proton transfer reaction in 2-aminopyridine dimer was investigated by femtosecond pump−probe electron−ion coincidence spectroscopy and accompanying theory. Excited-state population dynamics were observed real time time-resolved mass spectroscopy, the respective excited-state character of locally excited proton/hydrogen states identified coincident electron spectra. Two channels for an ultrafast (sub-50 fs) a slower (∼75 ps) indicate that vibrational energy redistribution may lead to efficient trapping state. Spectroscopic evidence unexpected hydrogen-transfer photoexcited aminopyridine monomer is also presented.
