## Abstract We propose that the term β€œabsolute conformation” be used when one of the chiroptical properties is correlated with one of a pair of enantiomeric conformations. We present examples of compounds for which absolute conformations are known, as well as their syntheses, enantiomer resolution,

The absolute configuration and the conformation of 9,10-trans-disubstituted 9,10-dihydrophenanthrenes, known chiral metabolites of phenanthrene-9,10-oxide, have been determined by circular dichroism. The absolute configuration assignment is based on the sign of the long-wavelength Cotton effect (A-b

The O-acetylmandelates and mandelates of endo-and exo-norborn-5-en-2-ol were prepared, both as a mixture and also as separate diastereomers. 1 H NMR spectroscopy of these derivatives was efficiently used to determine the enantiomeric ratios and to predict the absolute configuration of the alcohols.
