Direct measurement of H (super +) activity inside cross-linked functional polymers using nitroxide spin probes

Article Abstract:

In the study conducted the application to determination of ionization constants of functional groups and to the investigation of the hydrolysis and sorption of copper on different types of sorbents are described. It is suggested that the developed method can be useful for the investigation of ion exchangers, and it has the potential to increase the interactions in other porous systems.

A two-dimensional magic-angle decoupling and magic-angle turning solid-state NMR method: an application to study chemical shift tensors from peptides that are nonselectively labeled with (super 15)N isotope

Article Abstract:

Means for obtaining resolved dipolar shift powder patterns are demonstrated by use of two-dimensional magic-angle decoupling and magic-angle turning technique. These patterns have the same line shapes as those of the corresponding stationary patterns.
