The stereochemistry of hydroxyl groups in sesquiterpene lactones of pseudoguaiane type was discussed from their infrared absorption spectra. It was considered that stereochemical relation of hydroxyls in unknown sesquiterpene lactones could be predicted from the relative measured values such as the inter-and intra-molecular hydrogen bonding of the hydroxyls.
