(12) Two 13C spins differ in chemical shift by 50 ppm. Assuming that the rotating frame rotates at a frequency exactly halfway between the two spins: a. Calculate the frequency offsets (in Hz) of the two vectors corresponding to the two spins. The external magnetic field Bo is 14.1 T. b. If the two C spins are coupled to each other by a J-coupling constant of 50 Hz, calculate the frequency offsets of all of the vectors corresponding to the two spins.
