A partial differential equation for pseudocontact shift [PDF]

open access: yes, 2014
It is demonstrated that pseudocontact shift (PCS), viewed as a scalar or a tensor field in three dimensions, obeys an elliptic partial differential equation with a source term that depends on the Hessian of the unpaired electron probability density.

Pushing the sensitivity boundaries of X-band EPR cryoprobe using a fast microwave switch

open access: yesJournal of Magnetic Resonance Open
We present a new design of an X-band EPR cryoprobe based on a fast microwave switch and a cryogenic low-noise microwave amplifier that are placed close to the sample in the same cryostat.

Electron Paramagnetic Resonance Investigation of Radiation Effect on Certain Types of Drug Powders

open access: yesCumhuriyet Science Journal, 2018
In this study, gamma rays were applied to the sulfadimethoxine, pyrazinamide, and chloramphenicol in the dose range of 1-15 kilogray, in order todetect radiosensitivity of paramagnetic species, which are formed afterirradiation by electron paramagnetic ...
