Problem- Part (a) Calculate the Larmor frequency of a bare 11B nucleus in a magnetic field of 21.1 T. Assume the magnetic field is known exactly. Part (b) Calculate the resonance frequency for 11B in the same magnetic field when its magnetic shielding constant is 100 ppm. Assume the magnetic field is known exactly
