Redfield theory expressions for dipolar relaxation and cross-relaxation rates, isotropic tumbling in liquid phase. Spin-1/2 particles only at this point.
Syntax
[r1,r2,rx]=rlx_dip(B0,spins,dist,tau_c)
Parameters
B0 - magnet field, Tesla
spins - the spins involved, e.g. {'1H','15N'}
dist - inter-spin distance, Angstrom
tau_c - rotational correlation time, seconds
Outputs
r1 - two longitudinal relaxation rates, Hz r2 - two transverse relaxation rates, Hz rx - longitudinal cross-relaxation rate, Hz
Examples
For a carbon-proton pair in a small protein:
>> [r1,r2,rx]=rlx_dip(14.1,{'1H','13C'},1.5,1e-9)
r1 = 0.1791 0.6162
r2 = 1.2216 1.0031
rx = -0.0462
