This substantially revised and expanded new edition of the bestselling textbook, addresses the difficulties that can arise with the mathematics that underpins the study of symmetry, and acknowledges that group theory can be a complex concept for students to grasp. Written in a clear, concise manner...
xz,R_x, etc) and multiply together in the same way as the group operations. In some point groups, a symmetry causes two directional properties to mix. These directional properties must then be degenerate; they are bracketed together in the...

The amorphous chemical shift lineshape ultimately assumes the symmetry typical of isotropic motions. Separation of the lineshape into crystalline and amorphous parts also yields a satisfactory estimate of the crystallinity. The α relaxation is not detected in NMR measurements.

We identified a family of molecules that might exemplify this strategy. The compounds are three-coordinate with local pseudo-C3symmetry at the metal ion. In this point group, the lowest energy d-orbital is dz2and it has the same irreducible representation as an s-orbital; therefore, the s-...
