NMR Interactions: PAS Introducing a convenient representation for encoding this orientational dependence 1 A PAS =A iso 1 A−1/2 1 0 0 0 −1/2 1− 0 0 0 Isotropic shift: A iso =1/3Tr 〚 A〛 Strength of the anisotropy: Symmetry of the anisotropy (asymmetry parameter): A =A ZZ −A iso A = A XX −A YY / A
NMR Interactions: PAS Relative orientation of the PAS with respect to a reference frame (crystallographic axes, laboratory frame, ...) Factorization of X A provides the three Euler angles A , A , A X A =R A , A , A =exp −i A I z ⋅exp −i A I y ⋅exp −i A I z (x,y,z) is the PAS of the reference frame B 0 A ZZ In NMR the position of a line (single crystal) is dependent upon the six parameters: A iso , A , A , A , A , A A XX A YY
