摘要: Solvation processes play a crucial role in chemical reactions and biomolecular recognition phenomena. Although solvation dynamics of interfacial or biological water has been studied extensively aqueous solution, the results are generally averaged over several layers motion individual solvent molecules is difficult to capture. This review describes development application new experimental approach, namely, picosecond time-resolved pump–probe infrared spectroscopy size- isomer-selected aromatic clusters, which for first time single molecule can be followed real time. The intermolecular isomerization reaction triggered by resonant photoionization (pump), photodissociation (probe) at variable delay generates spectroscopic signature salient properties reaction, including rates, yields, pathways, branching ratios competing reactions, existence intermediates, occurrence back ...
