By suspending bovine rhodopsin in trehalose-water glass films, it is possible to trap photostates in the light-activation process. Because of the unusually high vitrification temperature of trehalose-water mixtures, this trapping can be accomplished
Phase-lifetime spectroscopy of photocycle processes: kinetic analysis of amplitude dispersion curves

Phase-lifetime spectroscopy has been recently used to obtain kinetic information on biological photocycles. A simple, general method is presented for deriving the amplitude response function for light-driven processes. These amplitude response functi

Phase-lifetime spectroscopy was used to measure the kinetics of light-driven proton transients and M intermediate decay of purple membrane. The kinetics were measured in distilled water and in 0.4 M KCl over the pH range of 5.3-8.8. The low ionic str

A ligand binding model of counterion association in finite length polyelectrolytes is presented. This model introduces counterion condensation features into a binding formalism. It agrees well with the predictions of other finite length models and is

Quantum time‐evolution propagators are derived for a particle on a fractal lattice. It is shown that the path of such a particle represents a self‐affine fractal. A relationship is obtained between the fractal dimension of the path (as determined

The combination of a wealth of structural data and impressive computational power provides detailed information pertaining to the structure and dynamics of biomacromolecules. A natural inclination is to incorporate this information into models to gai

A variety of statistical methods have been developed to explore correlations in protein and nucleic acid sequences. Such correlations have important implications for the evolution and stability of these macromolecules. Recently, a number of fractal a

Experimental data for the exchange of protons in tritiated lysozyme is reexamined by using a fractal model. The fraction of protons unexchanged, f, is seen to follow a stretched exponential, f infinity exp[(-t/tau)alpha], in the long time limit. Data

Fluorescence energy transfer can be used to investigate spatial distributions of acceptor molecules on surfaces or in membranes. In these applications energy transfer is observed from multiple donors to multiple acceptors. The fluorescence decay in s
