WebMar 25, 2024 · The Harvard physicists also show that the principal magic angle can be very precisely calculated and that its value is the same as that reported in experiments. They believe that exotic magic-angle phenomena could occur in other van der Waals layered devices, and they are now actively investigating these systems. 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, P2(cos θ) = 0, 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.
