Summary Near‐infrared spectra have been measured on a group of hydroperoxides of fatty acid esters and related substances. Only those substances having an −OOH group were found to absorb at 1.46 and 2.07 μ. Dialkyl peroxides and ozonized unsaturated substances had no such maxima in their near infrared spectra although they had high iodometric peroxide values. In a study of the thermal decomposition of methyl oleate hydroperoxide and a study of the autoxidation of methyl linoleate, the intensity of absorption at 1.46 and 2.07 μ paralleled the iodometric peroxide value.
