摘要: Abstract A general formula is derived (containing eigenvalues and eigenfunctions of some diffusion equation) for activation energies from NMR-relaxation times rotating molecular groups. Numerical calculations a trigonometric three well potential in the strong damping (Smoluchowski) limit show that there may be considerable difference between energy barrier height. In low fairly good agreement.
