paramagpy.metal.Metal.ccr

Metal.ccr(position, gamma, dipole_shift_tensor)

Calculate R2 cross-corelated relaxation due to DDxDSA

If the metal has an anisotropic magnetic susceptibility, this is taken into account.

Parameters

• position (array of floats) – three coordinates (x,y,z) this is the position of the nuclear spin

• gamma (float) – the gyromagnetic ratio of the relaxing spin

• dipole_shift_tensor (3x3 array of floats) – this is the dipole shift tensor arising from the nuclear spin of the coupling partner

Returns

value – The R2 differential line broadening rate in /s

Return type

float
