Analysis of NMR Spectra
A Guide for Chemists
Chapter
Nowadays dielectric spectroscopy covers the frequency range from 10−6 Hz to 1010 Hz by using computer controlled impedance analyzers [1–10], network analyzers as well as time domain spectrometers [11,12]. At high...

In a recent Nature leading article1 the possibility of the occurrence of resonance absorption at microwave frequencies in DNA was discussed in terms of the latest available theoretical2 and experimental evidence3

The dielectric properties of LiCl, CaCl2·2H2O, Ca(NO3)2·4H2O, Al(NO3)3·9H2O in 1-propanol solutions have been investigated using the dielectric time domain spectroscopy technique. The dielectric spectrum of 1-pro...

Chapter and Conference Paper
Nuclear magnetic resonance is possible because a number of nuclei possess intrinsic magnetic moments. The existence of an intrinsic magnetic moment is intimately related to the angular momentum properties of t...
Chapter and Conference Paper
A common method for analysing NMR spectra proceeds as follows. For a given type of spin system, theoretical formulae are derived for the frequencies and relative intensities of all the allowed transitions. On ...
Chapter and Conference Paper
The basic quantum mechanics required will be described with a sequence of postulates and definitions with a few comments interpolated. The treatment does not claim maximum rigour and elegance but is intended t...
Chapter and Conference Paper
The structure of a high-resolution NMR spectrum depends among other things on whether the magnetic nuclei of the molecule may be divided into groups of equivalent spins, or not. It is important to distinguish ...
Chapter and Conference Paper
Simple first order spectra arise from spin systems in which each basic group consists of one single spin or one single group of magnetically equivalent nuclei. The line structure of a basic multiplet can then ...
