paramagpy.metal.Metal.pcs_gradient

Metal.pcs_gradient(position)

Calculate the gradient of the psuedo-contact shift at the given postition. This equation uses analytic partial derivatives calculated in Mathematica.

Parameters

position (array floats) – the position (x, y, z) in metres

Returns

gradient – the [x,y,z] gradient vector for the pseudo-contact shift in parts-per-million (ppm) per metre

Return type

array of floats
