Converts point electron and nuclear coordinates into a hyperfine interaction tensor.
Syntax
A=xyz2hfc(exyz,nxyz,isotope)
Parameters
exyz - Cartesian coordinates of the electron,
a 1x3 row vector in Angstrom
nxyz - Cartesian coordinates of the nucleus,
a 1x3 row vector in Angstrom
isotope - isotope specification, e.g. '13C'
Outputs
A - hyperfine coupling tensor, Gauss
Notes
Gauss units are used for hyperfine couplings because they do not depend on the electron g-tensor.
The tensor returned is the one that enters the spin Hamiltonian as S*A*I; it does not scale with the number of unpaired electrons because the electron spin operator already carries that magnitude.
