Abstract: The ever increasing importance of physical methods in the elucidation of the structure and configuration of carotenoids is reviewed.The use of solvent partition, chromatography, X-ray crystallography, infra-red spectroscopy and optical rotary dispersion are briefly discussed.Special emphasis is given to the application of absorption spectroscopy and to 220 MHz proton magnetic resonance spectroscopy of carotenoids.Mass spectroscopic studies of the characteristic fragmentation of the carotenes, and a possible mechanism for the fragmentation of the polyene chain, are discussed in detail. * * *). max.nm ( petrote um ether) ~apocarotenals 15,15~dehydrop -apocarolenal s
