Time-resolved gamma spectroscopy of single events

Time Resolved Single Molecule Spectroscopy

A new method based on the calculation of autocorrelation functions for spectra measured at a high acquisition rate is developed to study spectral dynamics of single molecules. The technique allows for spectroscopy with time resolutions down to the luminescence lifetime. The method is used to study spectral diffusion in two-photon excitation spectra of diphenyloctatetraene molecules doped in an ...

Time-Resolved Spectroscopy of Proteins

changes upon e.g. unfolding, substrate binding or Optical absorption of proteins in the region of 250other catalytical processes. Furthermore, single Trp 300 nm (near-UV) is governed by the aromatic mutants provide the possibility to examine protein amino acid residues phenylalanine (Phe), tyrosine dynamic at individual sites of the protein with time(Tyr) and tryptophan (Trp) [1]. Compared with...

Time-resolved subnatural-width spectroscopy.

Spectra that are narrower than the natural width of decaying states can be achieved by beginning the observation of signals at a fixed delay time after excitation rather than immediately afterward. These signals are weaker (and noisier) than the full, time-unresolved signals. Applications of this line-narrowing technique to precision spectroscopy are discussed, and the properties of the resulti...
