Try Physical Chemistry of Macromolecules, by Charles Tanford.
If I remember correctly, and it's been a while, it's a statistically
defined parameter that describes the sphere swept out by the "mass
elements" of the peptide chain (or other atoms of whatever molecule).  IF I
remember correctly it's the radius measured in light scattering
experiments, though there are other ways.
