Preferred Label : radius of gyration;
Detailed label : radius of gyration, s;
IUPAC definition : A parameter characterizing the size of a particle of any shape. For a rigid particle
consisting of mass elements of mass m i, each located at a distance r i from the centre
of mass, the radius of gyration, s, is defined as the square root of the mass-average
of r i 2 for all the mass elements, i.e. \[s \sqrt{\frac{\sum _{i}m_{i}\ r_{i} {2}}{\sum
_{i}m_{i}}}\] For a non-rigid particle, an average over all conformations is considered,
i.e. \[\sqrt{ s {2} } \frac{\sqrt{ \sum _{\begin{array}{c};
