## Abstract Electrospray ionization tandem mass spectrometry (ESI‐MS/MS) was used to investigate the fragmentation pattern of ten sesquiterpene lactones of the goyazensolide type under low‐energy collision‐induced dissociation (CID) using a triple quadrupole mass spectrometer. The analysis revealed

Abstract
We describe the reassignment of ^13^C NMR signals of goyazensolide based upon 1D and 2D techniques, and discuss its conformation and stereochemistry as obtained from the analysis of its proton spin–spin coupling constants, NOE measurements and molecular mechanics calculations using MM3* force field.

The 220 MHz 'H spectra of isoverbanone, nopinone and verbanone are reported. The spectra of the first two are completely assigned but that of verbanone only partially. The coupling constants obtained provide information about the conformation of these molecules. The isoverbanone molecule is almost Y
