Spin hyperpolarization can dramatically increase signal intensities in magnetic resonance experiments, providing either improved bulk sensitivity or additional spectroscopic detail through selective enhancements. While typical hyperpolarization appro

The effects of γ-radiation sterilization on the parenteral excipient L-histidine were analysed by means of EPR spectroscopy. The irradiation process was found to induce the formation of a deamination radical which was persistent in the solid state.

Two-dimensional Fourier transform ion cyclotron resonance mass spectrometry (2D FTICR MS or 2D MS) allows direct correlation between precursor and fragment ions without isolation prior to fragmentation. The method has been optimized for the analysis
