β¦ Synopsis
Application of the Octant Rulels3 to interpret n-s* Cotton effects (CE's) of chiral ketones with deuterium perturbers4 has received very little experimental investigation aside from the recent work of Djerassi et al. 4 on chiral (3R)-deuteriocyclopentanone. The latter, despite its conformational mobility, exhibited negative circular dichroism (CD) CE's (AE~D~ = -0.019 at 2SΒ°C

CHIROPTICAL Methods have been used to determine the absolute configuration of twistane by two groups of workers. 2'3Y4 Adachi et a1.,2 by application of the octant rule 5 to the positive Cotton effect of the intermediate ketone &J-L, predicted its absolute configuration to be enantiomeric with that
MCD measuremepts have been used to estimate the ground-and excited-state magnetic moments and zero-field splittings for the 4A2 -'E('D) km&ion in CssCoCls. Most of the recenrextensive work on magnetic circular dichroism (MCD) [l] has concentrated on situations in which the linewidths have been large
