Question

Nuclear magnetic resonance (NMR) spectroscopy is a powerful method, in which transitions occur between different angular momentum states of an atomic nucleus. Let us consider the case of 23Na, a biologically important element, for which the angular momentum quantum number is S = 3/2. (a) Calculate the magnitude ISI of the angular momentum of the 23Na nucleus in SI units: (b) Sketch a diagram of the possible orientations of the angular momentum relative to an arbitrary axis and label them by the values of the z-component in units of ħ:
