ABSTRACT

Nuclear magnetic resonance (NMR) is widely used for scienti•c research and qualitative and quantitative analysis during manufacturing. Recent technical progress has greatly improved NMR spectrometers and developed methods to extend the sphere of its applications. Since its invention, NMR technology proceeded in two directions: (1) high resolution NMR that can analyze lines from millionths to thousandths of oersted (Oe) in width and (2) low resolution NMR for analyzing lines of tenths of oersteds and larger. Spectrometers implementing these methods include various types of technologies and instrumentation. Their only similarity is functioning is based on NMR principles.
