Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Highly structured fluorescence is reported for C60 mols. isolated in Ne and Ar matrixes. Their excitation spectra are similar to the gas-phase 2-photon ionization spectrum of C60. Most of the bands seen in emission can be attributed to Herzberg-Teller or J ...
The environment is important for the exact course of a chemical reaction. As an example of the strong influence of the environment on the reaction, this work studies the isomerization reaction of the chromophore retinal in the binding pocket of the protein ...
This thesis analyzes the properties of heavily doped nanocrystalline titanium dioxide. Thin films were deposited by magnetron sputtering with either water vapor as reactive gas or a periodically interrupted oxygen supply. The samples were at the same time ...
Rydberg-Rydberg transitions are induced by absorption from the lowest Rydberg state of NO A 2S+ (3ss) in Ar matrixes, which is excited by an ArF laser at 193.3 nm. The depopulation of the A(v = 0) level to higher Rydberg states is probed by depletion of it ...
The aim of this thesis is to optimise and gain fundamental information on two applications of photomedicine using fluorescence imaging and spectrofluorometry: (1) the detection of early bronchial cancer by autofluorescence imaging and (2) the endometrial a ...
The absorption and fluorescence spectra of silver trimers isolated in an Ar matrix show the existence of three distinct lattice sites whereby the population of each site depends on the conditions of matrix preparation. Irradiation of certain absorption ban ...
The spectroscopy of Hg2 mols. in Ne matrixes was studied using absorption, excitation and emission spectroscopy. Emission spectra show fluorescence from the lowest A0g+ and the B1g states, sepd. by .apprx.1500 cm-1, to the ground state X0+g. Their excitati ...
Highly structured fluorescence and fluorescence excitation spectra of C70 in Ne matrixes are reported. Fluorescence from both S1 and S2 states is obsd., and these are identified as being of A2' and E1' and have energies of 15,524 cm-1 and 15,691 cm-1, resp ...
To better understand the complex photophysics of the amino acid tryptophan, which is widely used as a probe of protein structure and dynamics, we have measured electronic spectra of protonated, gas-phase tryptophan solvated with a controlled number of wate ...
Information on the temporal order, the kinetics, and the energetics of each of the reaction intermediates is required in order to fully elucidate the mechanism of catalytic interaction of G proteins with their receptors. Intrinsic monitors, such as light s ...
