In mathematics, a tensor is an algebraic object that describes a (multilinear) relationship between sets of algebraic objects related to a vector space.Objects that tensors may map between include vectors and scalars, and even other tensors.Tensors can take several different forms - for example: scalars and vectors (which are the simplest tensors), dual vectors, multilinear maps between.

In the second part of Eq. (4) the orientation dependent variation of the Zeeman splitting is expressed by a (3x3) g interaction matrix. The information about the symmetry of the inner fields is thus transferred to a g matrix and can be obtained experimentally by determining the principal values of this matrix. In general the g matrix will be orthorhombic and is expressed in its principal axes. culation of the g tensor for paramagnetic defects in solids, except possibly within a cluster approximation.

The influence of g tensor anisotropy on spin dynamics of paramagnetic centers having real or effective spin of 1/2 is studied. The g anisotropy affects both the excitation and the detection of EPR signals, producing noticeable differences between conventional continuous-wave (cw) EPR and pulsed EPR spectra. The magnitudes and directions of the spin and magnetic moment vectors are generally not. However, the quality of the correlation with experimental data worsens due to a significant overestimate of some intermediate g‐tensor values. The worse performance of the BHPW91 functional in these cases is accompanied by spin contamination. Although none of the functionals tested thus appears to be ideal for the treatment of electronic g‐tensors in transition metal complexes, the B3PW91. The complex structure of the valence band in many semiconductors leads to multifaceted and unusual properties for spin-3/2 hole systems compared to common spin-1/2 electron systems. In particular, two-dimensional hole systems show a highly anisotropic Zeeman interaction.

Note that the sum of tensors at different points in space is not a tensor if the 's are position dependent. However, under linear coordinate transformations the 's are constant, so the sum of tensors at different points behaves as a tensor under this particular.
