Structure and stability of common sesquiterpenes

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2002
We present data on the electronic structure, polarity and relative stability of 14 common sesquiterpenes. The data were obtained by a combination of spectroscopic and high-level theoretical analysis. The discussion also includes comments on possible implication of molecular properties for physiological behaviour.

Sesquiterpenes—IV

Tetrahedron, 1963
Abstract A simple qualitative procedure is outlined for the conformational analysis of cycloheptane derivatives with particular attention to the natural perhydroazulenes. The procedure allows discrimination amongst different configuration and conformational isomers on grounds of thermodynamic stability.
