paramagpy.metal.Metal.fast_ccr¶
- Metal.fast_ccr(posarray, gammaarray, dstarray)[source]¶
Vectorised version of
paramagpy.metal.Metal.ccr()
This is generally used for speed in fitting DDxDSA data
If the metal has an anisotropic magnetic susceptibility, this is taken into account.
- Parameters
posarray (array with shape (n,3)) – array of positions in meters
gammaarray (array with shape (n,3)) – array of gyromagnetic ratios of the spins
dstarray (array with shape (n,3,3)) – array of nuclear dipole shift tensors arising from the coupling partners
- Returns
rates – The R2 differential line broadening rates in /s
- Return type
array with shape (n,1)
