Pms2chi.m

Runs a least squares fitting procedure on top of Equation 10 from http://dx.doi.org/10.1039/c4cp03106g to extract the susceptibility tensor from DFT hyperfine coupling tensors and experimentally observed paramagnetic (contact + pseudocontact) shifts.

Syntax

    [chi,err]=pms2chi(hfcs,shifts,isotopes)

Parameters

       hfcs   - cell array of 3x3 hyperfine coupling tensors
                in Gauss

     shifts   - vector of the observed pseudocontact shifts,
                excluding the diamagnetic contribution, ppm

   isotopes   - cell array of character strings specifying
                isotopes that exhibit each of the chemical
                shifts supplied, for example {'1H','13C'}

Outputs

        chi   - the fitted magnetic susceptibility tensor,
                cubic Angstroms

        err   - least squares error

Examples

See the paramagnetic shift getting started guide.

Notes

Gauss units are used for hyperfine couplings because they do not depend on the electron g-tensor.
