The absoluteconfiguration of the norlignan (+)-nyasol was determined to be S by comparison of the experimental vibrational circulardichroism data with first-principle calculations taking into account the eight lowest energy conformations. The established absoluteconfiguration of (+)-nyasol enables establishment of the absoluteconfiguration of (-)-hinokiresinol, which is concluded to be S. A total
