Journal ArticleDOI
Polyene spectroscopy: The lowest energy excited singlet state of diphenyloctatetraene and other linear polyenes
Bruce S. Hudson,Bryan E. Kohler +1 more
TL;DR: In this paper, a review of the available information on diphenyl polyenes is presented and a correlation of the oscillator strength of the fluorescence transition as deduced from the emission lifetime with the separation of the low energy excited states for a number of polyenes are noted.
Journal ArticleDOI
Tunable Laser Resonance Raman Spectroscopy of Bacteriorhodopsin
TL;DR: It is concluded that the observed C=N stretch at 1622 cm(-1) in the room temperature spectra, which in an earlier study by Mendelsohn was interpreted as evidence for an unprotonated linkage in bacteriorhodopsin, results from the presence of the 412 nm complex.

Visual-pigment spectra: implications of the protonation of the retinal Schiff base.
TL;DR: The most plausible specific model of chromophore-protein interactions is one in which the protonated Schiff base is closely associated with its counterion and where additional negatively charged or polar groups are positioned by the protein in the vicinity of the ring half of the Chromophore.

Color tuning in rhodopsins: the mechanism for the spectral shift between bacteriorhodopsin and sensory rhodopsin II.
Michael Hoffmann,Marius Wanko,Paul Strodel,Peter H. König,Thomas Frauenheim,Klaus Schulten,Walter Thiel,Emad Tajkhorshid,Marcus Elstner +8 more
TL;DR: The results indicate that several sources contribute to the spectral shift between bR and sRII, and the main factors are the counterion region at the extracellular side of retinal and the amino acid composition of the binding pocket.
