The magic angle is a precisely defined angle, the value of which is approximately 54.7356°. The magic angle is a root of a second-order Legendre polynomial, and so any interaction which depends on this second-order Legendre polynomial vanishes at the magic angle. This property makes the magic angle of particular importance in magic angle spinning solid-state NMR spectroscopy.

Famous quotes containing the words magic and/or angle:
“A full bosom is actually a millstone around a woman’s neck: it endears her to the men who want to make their mammet of her, but she is never allowed to think that their popping eyes actually see her. Her breasts ... are not parts of a person but lures slung around her neck, to be kneaded and twisted like magic putty, or mumbled and mouthed like lolly ices.”
—Germaine Greer (b. 1939)
“I fly in dreams, I know it is my privilege, I do not recall a single situation in dreams when I was unable to fly. To execute every sort of curve and angle with a light impulse, a flying mathematics—that is so distinct a happiness that it has permanently suffused my basic sense of happiness.”
—Friedrich Nietzsche (1844–1900)
