Slow-motion ESR spectra

CALCULATING SLOW-MOTION ESR SPECTRA OF SPIN-LABELED POLYMERS... 

This chapter presents a detailed description of the analysis of slow-motional ESR spectra of spin-labeled polymers, using the SLE-based ESR line shape calculation developed by the Freed group at Cornell (EPRLL, as originally named by Schneider and Freed ° ). We will only present such details of the calculation as may be needed to understand how it may be most efficiently applied to ESR line shape analysis. Detailed expositions of the theory underlying the SLE equation and its implementation may be found elsewhere. " ... 

The physical parameters in the models described above are most usually obtained fi om experimental slow-motional ESR spectra using nonlinear least-squares (NLLS)... 

Other theoretical approaches to the theory of slow-motional ESR spectra of nitroxides were also developed, aimed at solving specific problems. However, none of these affords a comprehensive treatment of the subject comparable with the approach described above.
