 AnnotationAssertion(rdfs:comment <http://nmrML.org/nmrCV#NMR:1400283> "Continuous wave NMR spectrometers are similar in principle to optical spectrometers. The sample is held in a strong magnetic field, and the frequency of the source is slowly scanned (in some instruments, the source frequency is held constant, and the field is scanned).
