Nuclear magnetic resonance spectroscopy

1986
Nuclear 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.

Solution Nuclear Magnetic Resonance Spectroscopy

2012
Solution 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, 2005
In 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

2013
Nuclear 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

2015
This 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.

Nuclear Magnetic Resonance Spectroscopy

1972
The first observations of the nuclear magnetic resonance (NMR) phenomena were reported in 1946 by Purcell [1] at Harvard University and by Bloch [2] at Stanford University. Since that time, NMR spectroscopy has experienced a remarkable growth and is presently one of the most useful instrumental techniques for the Study of chemical systems.
