Quantum-Indeterminate Proton Positions in Ultrafast Excited-State Intramolecular Proton Transfer.

Minhyuk Lee, Changmin Lee, JunWoo Kim

Although molecular vibrations are fundamentally described within a quantum mechanical framework, nuclear motion in condensed-phase chemistry is typically treated semiclassically, because direct experimental signatures of quantum behavior are difficult to access. Excited-state intramolecular proton transfer (ESIPT), which occurs before significant intra- and intermolecular perturbations can influence the system, provides a unique opportunity to probe such regimes. Here we investigate the ESIPT dynamics of [2,2'-bipyridyl]-3,3'-diol (BP(OH)
