Streak Camera Methods In Nucleic Acid And Protein Fluorescence Spectroscopy

The photoelectronic streak camera can clearly resolve picosecond electronic and molecular processes occurring in DNA and in proteins. Particularly appropriate examples are: fluorescence kinetics of nucleic acids which are sensitive to structure and base stacking interactions; fast rotational depolarization of emission from tyrosine sidechains in proteins; excited-state molecular dynamics as measured by time-resolved emission spectra.
