โœฆ Synopsis


Nitroxide radjcd parmagnetic resonance spe&a tire calculated as a'funckon of rotational ~m~eiatio~ time (~2) ' by the numerical solution ofdiifusion~oupled Bloch equations. For a dilute aqueous solution of spin-labeled oxqi-.

; hemoglobin, a Q of 26 r 2 nsec is obtained. This timi: increases linealy with viscosity as sucrose is: added to thz solution.

We explore the use of feed forward artificial neural networks for determining rotational correlation times from slow motional nitroxide electron spin resonance spectra. This approach is rapid and potentially eliminates the need for traditional iterative fitting procedures. Two networks are examined:

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
