Paramagnetic Relaxation Enhancement Restraints
Paramagnetic relaxation enhancement can be used to derive a distance
estimate. The transverse relaxation rate is given by the
Solomon-Bloembergen equation:
|
(34.1) |
where is the distance between a proton and the paramagnetic
center, is a collection of constants (depending on atom
types), is the
correlation time and is the proton's Larmor frequency.
The energy term takes the form
|
(34.2) |
where is the estimated uncertainty in the measured
values of .
