Fluorescence spectra of organic dyes in solution: a time dependent multilevel approach†
Abstract
Classical all-atom molecular dynamics (MD) simulations and quantum mechanical (QM) time-dependent density functional theory (TD-DFT) calculations are employed to study the conformational and photophysical properties of the first emitter excited state of tetramethyl-rhodamine iso-thiocyanate fluorophore in aqueous solution. For this purpose, a specific and accurate force field has been parameterised from QM data to model the fluorophore’s first bright excited state. During the MD simulations, the consequences of the π → π* electronic transition on the structure and microsolvation sphere of the
