Prism-based multicolor fluorescence correlation spectrometer

Theo Lasser, Marcel Leutenegger

We report the design and application of a prism-based detection system for fluorescence (cross) correlation spectroscopy. The system utilizes a single laser wavelength for the simultaneous excitation of several dyes of different emission spectra. Fluoresce ...

Influence of the protein environment on spectroscopy and ultrafast dynamics of retinal in bacteriorhodopsin

Selma Schenkl

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 ...

High resolution photodetachment spectroscopy of negative ions via slow photoelectron imaging

Andreas Osterwalder

A technique for high resoln. anion photodetachment spectroscopy is presented that combines velocity map imaging and anion threshold photodetachment. This method, slow electron velocity-map imaging, provides spectral line widths of better than 1 meV. Spectr ...

Ultrafast structural dynamics in electronically excited solid neon. I. Real-time probing of the electronic bubble formation

Majed Chergui, Franco Vigliotti, Luigi Bonacina

The dynamics of electron bubble formation upon excitation of the A(3ss) Rydberg orbital of NO in solid Ne was studied by conventional spectroscopy and fs pump-probe spectroscopy. The fs pump pulse initiates the formation of a bubble by the expansion of the ...

Ultrafast expansion and vibrational coherences of electronic 'Bubbles' in solid neon

Majed Chergui, Franco Vigliotti

The dynamics of electron bubble formation upon excitation of the A(3ss) Rydberg orbital of NO in solid Ne was studied by femtosecond pump-probe spectroscopy. The authors observe an ultrafast expansion of the bubble, followed by a vibrational recurrence in ...

Spectral and kinetic fluorescence properties of native and nonisomerizing retinal in bacteriorhodopsin

Majed Chergui, Stefan Haacke, Selma Schenkl

Steady-state and picosecond (ps) fluorescence studies of wild-type bacteriorhodopsin (wt-bR) and of a nonisomerizing analog locked in the all-trans configuration have been performed. Extending earlier work done by femtosecond absorption spectroscopy, we ob ...

Raman and fluorescence spectra of size-selected, matrix-isolated C14 and C18 neutral carbon clusters

The surface plasmon polariton-enhanced Raman spectra of size-selected, matrix-isolated C14 neutral clusters are presented along with the calculated vibrational frequencies for the ring and linear chain isomers. The Raman spectra show resonance enhancement ...
