Calculate the Larmor (resonance) frequency of hydrogen and other nuclei in a magnetic field, as used in MRI and NMR, free online.
À propos de cette calculatrice
Nuclei precess at f = (γ ÷ 2π) · B, where γ/2π is the gyromagnetic ratio: ¹H 42.577 MHz/T, ¹³C 10.708, ¹⁹F 40.052, ³¹P 17.235, ²³Na 11.262. A 3 T MRI scanner operates near 127.7 MHz for protons.
