Hybrid Monte Carlo simulations of vertical electronic transitions in acetone in aqueous solution

Abstract: A simulation of the n → π * absorption and the π * → n fluorescence of acetone in aqueous solution is reported. The model has an explicit solvent representation with an effective ab initio treatment of the solute. The model attempts to balance quantum chemistry, intermolecular interactions and statistical thermodynamics. It includes a non-electrostatic perturbation on the solute which models the solute-solvent exchange repulsion and the restriction put on the electronic structure of the solute by the antisymme… Show more

“…The acetone n → π * solvatochromic shift has also deserved considerable attention 46,57,[67][68][69][70][71][72][73][74][75][76][77][78][79][80][81] . Less is known about the Rydberg states, as well as other higher excitations.…”

“…Para isso foram usadas as geometrias de equilíbrio otimizadas para os estados eletrônicos fundamental e primeiro excitado, mostradas na figura 6. estado excitado apresenta um momento de dipolo ligeiramente menor que na sua geometria de equilíbrio. Esse esquema é similar ao obtido por Öhrn e Karlström [154] . Os valores médios convergidos das cargas dos sítios atômicos do soluto na presença do solvente são também mostrados na tabela 6.1.…”

“…[153] ROKS/CPMD 3.85 4.10 0.25 2015 Coutinho e Canuto [151] Georg et al [78] INDO Voltando ao estudo do espectro de emissão, temos que o deslocamento espectral da banda de emissão obtido por Öhrn e Karlström [154] está entre 160 e 400 cm -1 . (Por conveniência e melhor comparação com outros resultados reportaremos o deslocamento espectral cm -1 ).…”
