What Does ESIPT Stand For?

ESIPT stands for Excited State Intramolecular Proton Transfer

ESIPT, or Excited State Intramolecular Proton Transfer, is a photophysical process where a proton is transferred within a molecule upon excitation to an electronic excited state. This phenomenon plays a crucial role in various fields, including photochemistry and molecular biology, as it influences the molecule's stability, reactivity, and spectral properties. ESIPT mechanisms are essential for understanding the behavior of chromophores in light-harvesting systems and are leveraged in the design of fluorescent probes and sensors.
