Retrieval of solid-state 31P nuclear magnetic resonance (NMR) chemical shielding parameters: proposal of an approach concerning variable-temperature 31P NMR mass spectra of urea phosphate and comparison of different methods.
Several methods are used to retrieve the principal components of the 31P chemical shielding tensor from variable-temperature 31P NMR spectra of urea phosphate (both static and spinning at the magic angle at low speeds). A complementary approach is proposed for the study of small changes in these parameters, based on the measurement of selected side-band intensities which are most sensitive to changes in sigma.
