13. Modelo discreto de solvente. Solvatocromismo no espectro de absorção molecular / Discrete model of the solvent. Solvatochromic at the absorption spectrum molecular.
Um procedimento baseado no uso sequencial de simulação Monte Carlo e cálculos de Mecânica Quântica é proposto e usado para o tratamento de efeitos de solvente, com especial atenção parao sovatocromismo no espectro de absorção molecular. A ideia básica é realizar simulações clássicas com o método Monte Carlo para gerar estruturas supermolecula

14. Photophysics of a neurotransmitter: ionization and spectroscopic properties of serotonin.
The neurotransmitter serotonin plays a modulatory role in the regulation of various cognitive and behavioral functions such as sleep, mood, pain, depression, anxiety, and learning by binding to a number of serotonin receptors present upon the cell surface. The spectroscopic properties of serotonin and their modulation with ionization state have been studied.

15. Laurdan solvatochromism: solvent dielectric relaxation and intramolecular excited-state reaction.
Absorption, steady-state, and time-resolved fluorescence measurements have been performed on laurdan dissolved either in white viscous apolar solvents or in ethanol as a function of temperature. The heterogeneity of the absorption spectra in white oils or in ethanol is consistent with semiempirical calculations performed previously on Prodan. From steady-sta
