โœฆ Synopsis


It is shown how the stochastic Liouville approach of Freed, Bruno. and Polnaszek for describing ESR lineshapes in the slow motional region may be applied to the ELDOR experiment. It is possible, in the slow motional region, to pump with a saturating microwave field at one resonant frequency corresponding to a particular orientation and observe effects from the rotational motion in transmitting the saturation to another resonant position. Some effects are illustrated by simulation of ELDOR spectra for a simple ESR line in the slow motional reson.

The two-dimensional Fourier transform ESR techniques of stimulated SECSY and ZD-ELDOR are shown to be powerful methods for the study of slow motions for nitroxides. Stimulated SECSY provides magnetization transfer rates, whereas 2D-ELDOR displays how ihe rotational motions spread the spins out from

Two-dimensional Fourier transform ESR has now been extended to the slow-motional and rigid limit regimes which require spectral bandwidths of 200-250 MHz and sub-nanosecond time resolution in echo decays. Two-pulse SECSY-ESR on nitroxides is shown to provide detailed structural information from the

A methodology for obtaining pure absorption two-dimensional electron spin resonance spectra is presented for the case of large inhomogeneous broadening and/or slow motions. For slow motions, the spectra consist of "complex Lorentzians" superimposed with complex weighting factors, presenting a challe
