Nuclear Magnetic Dipole and Electric Quadrupole Energy Relations

Calculations based on existing theory of nuclear magnetic dipole and electric quadrupole transitions provide general expressions in closed form relating I, μH₀, e²Qq, η, θ, and φ to experimentally determined frequencies νᵢⱼ. The angles θ and φ determine the orientation of H₀ in the principal axis system of ∇E. Methods of applying the expressions in specific situations are discussed. Application of the procedure to similar systems, such as the asymmetric rotator, is pointed out.
