1D ExperimentsHydrogen has two NMR-active nuclei: .H, always known as “the proton” (thus “proton NMR”), making up 99.98%, and .H, normally referred to as D for deuterium.

Worked ExampleFirst use the molecular formula and the equation given above to calculate the number of double bond equivalents. In this case (remembering to treat bromine as equivalent to hydrogen) the value is 1. The infrared spectrum shows a band at 1641 cm., which probably represents the C=C bond stretch, but in this case there . only be a C=C bond present!

Introductiong with liquid or solid samples; the combination of high resolution and magic angle spinning (HR/MAS) of solid samples provides a wealth of structural information which is complementary to that obtained by X-ray crystallography. The same suite of techniques, slightly adapted, is now available to thos
