magic angle n. Physics and Chemistry (in NMR spectroscopy) the angle (measured relative to the direction of the magnetic field) of an axis around which a solid sample can be spun such that interactions of its nuclei average to zero, namely 54° 44′, or tan⁻¹√2.

1965 Physical Rev. A. 140 1261/2 Equation (3) shows that at the ‘magic angle’ θ = cos⁻¹(1/√3), (5) the second moment in the rotating frame vanishes.

1992 Jrnl. Physical Chem. 96 389/1 Samples were spun at the magic angle at rates of up to 3kHz.
