The effect of high magnetic fields

Separation of pseudocontact and contact (including any ligand centered pseudocontact) contributions to the hyperline shifts of heme and axial ligand protons for oxidized rat microsomal cytochrome at 313 K (heme numbering as in Fig. 5.7B) [127] 

An equation for the effect of an axial magnetic anisotropy of a paramagnetic center on the pseudocontact shift is [3,109]

Radford (1961, 1962) and Radford and Broida (1962) presented a complete theory of the Zeeman effect for diatomic molecules that included perturbation effects. This led to a series of detailed investigations of the CN B2E+ (v — 0) A2II (v = 10) perturbation in which many of the techniques of modern high-resolution molecular spectroscopy and analysis were first demonstrated anticrossing spectroscopy (Radford and Broida, 1962, 1963), microwave optical double resonance (Evenson, et at, 1964), excited-state hyperfine structure with perturbations (Radford, 1964), effect of perturbations on radiative lifetimes and on inter-electronic-state collisional energy transfer (Radford and Broida, 1963). A similarly complete treatment of the effect of a magnetic field on the CO a,3E+ A1 perturbation complex is reported by Sykora and Vidal (1998). The AS = 0 selection rule for the Zeeman Hamiltonian leads to important differences between the CN B2E+ A2II and CO a/3E+ A1 perturbation plus Zeeman examples, primarily in the absence in the latter case of interference effects between the Zeeman and intramolecular perturbation terms. 

The influence of high magnetic fields on elastic properties of heavy-fermion materials can lead to interesting effects. One might think of three possible sources for anomalous behaviour ...
