11. When the g tensor is rotated about an axis parallel to the direction of one principal value, the same tensor is obtained after a 180° rotation. For the case of 90° jumps about the chain which is parallel to g3, a 2-jump formalism has therefore been used. This is also the reason for the fact that 60° jumps about the chain axis are identical with 120° jumps and can be treated by a 3-jump formalism. For g tensor rotations about an arbitrary axis, however, a rotation of 360° is necessary to obtain the original tensor. For 90° jumps about the CO bond, a restricted 4-jump formalism had to be used. We are indebted to Dr. Z. Luz for pointing out to us this subtle difference. 15) Y. Ben Taarit, J. C. Vedrine, C. Naccache, Ph. de Montgolfier, and P. Meriaudeau, J. Chem. Phys., 67, 2880 (1977).
