Frequency dependence of electron spin relaxation times in aqueous solution for a nitronyl nitroxide radical and perdeuterated-tempone between 250MHz and 34GHz

December 21, 2012 - Biller, J.R., et al., Frequency dependence of electron spin relaxation times in aqueous solution for a nitronyl nitroxide radical and perdeuterated-tempone between 250MHz and 34GHz.

First determination of the spin relaxation properties of a nitronyl nitroxide in solution by electron spin echoes at X-band: A comparison with Tempone

October 10, 2012 - This article describes no DNP results. However, it can be still of interest for the solution-state DNP community since it discusses relaxation times of nitroxide spin-labels.

Formal Theory of Spin-Lattice Relaxation

August 23, 2012 - Besides transferring electron polarization to the nuclei, spin lattice relaxation is a very important process for DNP.
