Soit Q un operateur positif quasi-compact SW un espace ordonne B, et soit t H Q(f) une perturbation reguliere de Q(0) = Q, p ar exemple du type transformee de Fourier de Q lorsque Q est un noyau. Sous certaines hypotheses sur t3 et Q, on demontre que Ie spectre peripherique de Q est cyclique, et que cette propriete s'etend a Q(t) au voisinage de t = 0. 0 Academic des SciencesHsevier, Paris

The study of the temperature effect on the infrared absorption of dicobaltoctacarbonyl, which has led to the discovery of a non bridged isomer, has been extended to 300 cm-l. In the spectrum of the non bridged form only two bands have been found in the range from 700 to 300 cni-1, as compared with 8
