Electronic Spectra and Quenching of Dimethylanilines

Dimethylanline의 Electronic Spectra와 消光

Abstract

Electronic spectra and quenching constants for ten N,N-dimethylanilines (DMA) have been determined. The $250m{\mu}$ absorption band (C band) of DMA was shown to be mainly responsible for the quenching. This band was confirmed as an $n{\to}{\pi}^{\ast}$ band through substituent and medium effects on the spectra shifts. The energy absorbed by this band then transfers to triplet and down to the lowest triplet state, $^{3}La$, where the energy is lost by non-radiative collisions.
