Journal of Pharmaceutical and Biomedical Analysis, 1998
Since drugs in clinical use are mostly synthetic or natural products, NMR spectroscopy has been mainly used for the elucidation and confirmation of structures. For the last decade, NMR methods have been introduced to quantitative analysis in order to determine the impurity profile of a drug, to characteristic the composition of drug products, and to ...

Concepts and Methods of Solid-State NMR Spectroscopy Applied to Biomembranes.
Chemical Reviews, 2017Concepts of solid-state NMR spectroscopy and applications to fluid membranes are reviewed in this paper. Membrane lipids with 2H-labeled acyl chains or polar head groups are studied using 2H NMR to yield knowledge of their atomistic structures in ...

Inner-product NMR spectroscopy: A variant of covariance NMR spectroscopy
Journal of Magnetic Resonance, 2018We propose a variant of covariance NMR spectroscopy, namely, inner-product NMR spectroscopy, originally suggested in Takeda (2015). The mathematical operation of inner-product NMR is the same as that of covariance NMR, except that subtraction of the average value of the variable is intentionally omitted, so that the correspondence of the spectrum with ...

In vivo nuclear magnetic resonance (NMR) spectroscopy has an assured role to play in medical research because it enables one to interrogate non-invasively a range of biochemical processes, both in the resting state and then serially when they are changing in response to some induced stress.
