Time-resolved fluorescence spectroscopy

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...

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...

Femtosecond time-resolved photoelectron spectroscopy.

The development of femtosecond time-resolved methods for the study of gas-phase molecular dynamics is founded upon the seminal studies of Zewail and co-workers, as recognized in 1999 by the Nobel Prize in Chemistry.1 This methodology has been applied to chemical reactions ranging in complexity from bond-breaking in diatomic molecules to dynamics in larger organic and biological molecules, and h...
