7-diethylamino coumarins exhibit large enhancement of fluorescence yield upon binding to bovine serum albumin. It is argued that the polarity-dependent twisted intramolecular charge transfer (TICT) process is responsible for the remarkable fluorescence sensitivity of these biological fluorophores to

The model of Grabowski et al. has been modified and used to account for the absence of a fluorescence band from the twisted form of molecules with torsional mechanisms. We have measured the ground and excited state spectroscopic properties of rhodamine B dissolved in a series of water-ethanol mixed
