Represented by matrix D<br />
D xx , D yy , D zz reflect molecular<br />
mobility along x, y, z axes.<br />
D xy , D xz , D yz reflect correlations<br />
between molecular displacements in<br />
perpendicular directions.<br />
Eigenvalues λ 1 , λ 2 , λ 3 indicate<br />
main diffusion direction<br />
