Nuclear magnetic resonance spectroscopy
Analytical Chemistry, 1988Nuclear magnetic resonance (NMR) spectroscopy is one of the most widely used instrumental methods, with applications ranging from the characterization of pure compounds by high-resolution NMR to the diagnosis of disease by magnetic resonance imaging (MRI).

Covariance nuclear magnetic resonance spectroscopy
The Journal of Chemical Physics, 2004Covariance nuclear magnetic resonance (NMR) spectroscopy is introduced, which is a new scheme for establishing nuclear spin correlations from NMR experiments. In this method correlated spin dynamics is directly displayed in terms of a covariance matrix of a series of one-dimensional (1D) spectra.

Nuclear magnetic resonance spectroscopy
Resonance, 2004Nuclear magnetic resonance in condensed matter was discovered simultaneously by Edward Purcell at Harvard and Felix Bloch at Stanford in 1946 using different instrumentation and techniques. Both groups observed the response of magnetic nuclei, placed in a uniform magnetic field, to a continuous radio frequency magnetic field as the field was tuned ...

Nuclear magnetic resonance spectroscopy
1986Nuclear magnetic resonance (NMR) spectroscopy is usually combined with infrared (IR) spectroscopy for the complete analysis of the structure of an unknown molecule. IR spectroscopy is used to detect a functional group in the sample, whereas NMR spectroscopy detects number of atoms and their type in sample.

Nuclear Magnetic Resonance Spectroscopy*
Methods, 2019Two molecules may have the same number and type of atoms, but their properties would change depending on how they are arranged (i.e., the bonds linking them and their orientation).

Solution Nuclear Magnetic Resonance Spectroscopy
2012Solution nuclear magnetic resonance (NMR) spectroscopy has come a long way in characterizing the structure and function of biological molecules since the first one-dimensional spectrum of protein was recorded about 30 years ago. To date (September 1, 2012), there are 9,521 solution NMR structures in the Protein Data Bank, compared to 74,009 determined ...

Microcoil nuclear magnetic resonance spectroscopy
Journal of Pharmaceutical and Biomedical Analysis, 2005In comparison with most analytical chemistry techniques, nuclear magnetic resonance has an intrinsically low sensitivity, and many potential applications are therefore precluded by the limited available quantity of certain types of sample. In recent years, there has been a trend, both commercial and academic, towards miniaturization of the receiver ...

Nuclear Magnetic Resonance Spectroscopy
2013Nuclear magnetic resonance (NMR) has developed into an important tool for investigating the structure and dynamics of biomacromolecules in solution, associated with membranes and in solids. This chapter provides an introduction to the theory of NMR and a description of basic concepts (excitation of NMR transitions, spin populations and coherence ...

Nuclear magnetic resonance spectroscopy
2015This chapter talks about the concept of nuclear spin, which focuses on nuclear magnetic moments and their study through nuclear magnetic resonance (NMR) spectroscopy. It uses the proton,1H, as the simplest example that illustrates how the phenomenon arises and describes the operation of a basic NMR spectrometer.
