rlx_csa.m

Redfield theory expressions for CSA relaxation, including contributions from the antisymmetric part.

Syntax

    [r1,r2]=rlx_csa(B0,isotope,Z,tau_c)

Parameters

   B0       - magnet field, Tesla

   isotope  - the spins involved, e.g. '15N'

   Z        - chemical shift tensor, 3x3
              matrix in ppm

   tau_c    - second rank (1/6D) rotational 
              correlation time, seconds

Outputs

   r1       - longitudinal relaxation rate, Hz

   r2       - transverse relaxation rate, Hz

Notes

CSA antisymmetry is usually negligible in diamagnetic systems, by can be very large for paramagnetic shielding.
