Twisted intramolecular charge transfer of ethyl p-(N,N-diethylamino)benzoate in the gas phase and in low-density non-polar supercritical fluids. A quantitative spectral resolution using principal component analysis and self modelling

Abstract

Twisted intramolecular charge transfer (TICT) is observed for ethyl p-(N,N-diethylamino)benzoate in the gas phase and in low-density supercritical ethane, and the emission bands of the locally excited and TICT states and their relative contributions to observed fluorescence spectra are determined using principal component analysis–self modelling spectral resolution.
