Study of Internal Motions in Globular Proteins by Temperature and Frequencies Dependencies of Protein Protons T 1

Minima of T1 at −100°C and 0°C and T1 limit for protein protons at increasing of concentration or viscosity of solution or protein molecular weight and considerable dispersion in T1 values higher and lower frequencies of globule rotation in solutions and T1 minimum at −100°C in protein powders were observed that due to various internal motions.
