The hydrogen and isobutane chemical ionization mass spectra of a number of carotenoids, with symmetrical and unsymmetrical end groups, have been examined. Similar spectra were obtained with each gas. Loss of fragments, characteristic of both the polyene chain and of the end groups were shown by all
