This paper reports values for the A and g magnetic tensor components f
or PD-Tempone in the rigid limit of the n-pentyl (5CB), n-hexyl (6CB),
n-heptyl (7CB), and n-octyl (8CB) cyanobiphenyl liquid crystals and f
or Tempo-Palmitate in the rigid limit of 5CB and 6CB. A unified approa
ch based on introducing a factor into the ''distortion theory'' expres
sion for obtaining probe order parameters S-ii is successfully tested.
The sign and value of this factor give the probability of alignment o
f the ith axis of the probe along the applied magnetic field.
