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:
“We’re not blind and we’re not fools. We’re just plain, sensible people who refuse to be fooled by a lot of supernatural nonsense.... There’s no magic in dried lizards and dead chickens.”
—Eric Taylor. Robert Siodmak. Frank Stanley (Robert Paige)
“It is a mistake, to think the same thing affects both sight and touch. If the same angle or square, which is the object of touch, be also the object of vision, what should hinder the blind man, at first sight, from knowing it?”
—George Berkeley (1685–1753)
