    Notes: [Auszug] Recent work by Jackson et cd.* and Privett et al.' on the linoleates has enabled further assignments to be made in this region. Trans-trans conjugation is characterized by an absorption band at 988 cm.-1, whereas ds-trans conjugation is characterized by absorption bands at 948 and 982 cm.-1. ...
