magnetic resonance spectrometry

Magnetic resonance spectra are indispensable today for studies in heterocyclic chemistry. Proton resonance spectra, the most common type, yield information regarding the number of hydrogen atoms in the molecule, their chemical environment, and their relative orientation in space. Mass spectra are used to determine not…

In an MR spectrometer (Figure 2) the amount of energy extracted from the superimposed field is continuously measured and recorded on a strip chart while the frequency of the field is slowly varied. The resulting record, or spectrum, is ordinarily a straight line—indicating that the sample is absorbing…
