Trosy eff.m

TROSY efficiency in a two-spin system. Returns the extent of the cancellation of the CSA contribution to the transverse relaxation by the DD-CSA cross-correlation.

Syntax

                eff=trosy_eff(B0,isotopes,xyz,csa)

Arguments

       B0       - magnet field, Tesla
       isotopes - a cell array with two character
                  strings, e.g. {'19F','13C'} spe-
                  cifying spin-1/2 isotopes
       xyz      - a cell array with two Cartesian
                  coordinate vectors in angstrom,
                  giving the locations of the two
                  nuclei
       csa      - 3x3 chemical shielding or chemi-
                  cal shift (does not matter here)
                  tensor of the first spin in ppm;
                  its isotropic part will be drop-
                  ped automatically

Outputs

       eff      - fraction of the CSA line width
                  that is compensated by DD-CSA
                  cross-correlation, 1 means that
                  the line width is purely dipolar
