These changes occur because the atomic configuration varies from the electron angular momentum being primarily coupled to the nucleus at a low external field to being principally coupled to the external magnetic field at a high field. Utilizing the Breit-Rabi formula and an atomic beam apparatus which deflected the atomic magnetic moments with inhomogeneous magnetic fields, Rabi, V

that the molecular beam deflection method could be adapted to measurements of the signs of nuclear magnetic moments by determining which transitions occurred when atoms went through a region of space in which the directions of the magnetic fields were successively reversecl.3 Rabi cleveloped the theory of such transitions in his imnortant naner entities!

By measuring the beam intensity as a function of frequency, one could thereby determine the spacing of the molecular energy levels. The first successful molecular beam magnetic resonance experiment was that of Rabi, S
