Hydrogen atoms are placed in an external 1.65-T magnetic field.
(a) The protons can make transitions between states where the nuclear spin component is parallel and anti parallel to the field by absorbing or emitting a photon. Which state has lower energy: the state with the nuclear spin component parallel or anti parallel to the field? What are the frequency and wavelength of the photon? In which region of the electromagnetic spectrum does it lie?
(b) The electrons can make transitions between states where the electron spin component is parallel and anti parallel to the field by absorbing or emitting a photon. Which state has lower energy: the state with the electron spin component parallel or anti parallel to the field? What are the frequency and wavelength of the photon? In which region of the electromagnetic spectrum does it lie?
