1. Espectroscopia eletrÃnica e solvataÃÃo de cromÃforos zwiteriÃnicos: um estudo ab initio
Pela simplicidade do tratamento teÃrico, fÃcil processabilidade, e possÃveis aplicaÃÃes em ciÃncias dos materiais, oligÃmeros conjugados representam uma classe especial de compostos orgÃnicos. A substituiÃÃo terminal dessas estruturas com grupos doadores (D) e aceitadores de elÃtrons (A) resulta em molÃculas (D - π - A) com propriedades Ãti

2. Estrutura eletronica e polarizabilidades de betainas
This thesis is dedicated to a theoretical study of the electronic structure and optical properties of betaine molecules carried at the semiempirical and ab initio levels. The charge distribution, the dipole moment and the linear (a) and first nonlinear (Ã) polarizabilities of a total of 66 betaine molecules belonging to 6 different families were calculated.

3. Direct observation of ultrafast folding and denatured state dynamics in single protein molecules
Single-molecule fluorescence resonance energy transfer (smFRET) experiments are extremely useful in studying protein folding but are generally limited to time scales of greater than ≈100 μs and distances greater than ≈2 nm. We used single-molecule fluorescence quenching by photoinduced electron transfer, detecting short-range events, in combination with
