The experimental evidence in favour of the interpretation of the yellow and green series of Cu2O as a second class (weakly forbidden) exciton spectra is discussed. The shape of the absorption lines has been studied in detail and compared with Toyozawa's theory. Good agreement has been found with the Lorentzian unsymmétrical type of lines predicted by the theory.Les faits fondamentaux montrant que les séries jaune et verte de la cuprite constituent des spectres excitoniques de deuxième classe sont rappelés et discutés. Le profil de l'absorption propre des raies est étudié en détail. Les résultats obtenus sont discutés et comparés à la théorie de Toyozawa sur le profil des raies excitoniques
