The absorption band spectrum of FCl 35 /FCl 137  is photographed in the region 5200—4600 A using a 5 m Ebert spectrograph. 27 bands of the O + ← 1 Σ + -system are analyzed and their origins calculated. The isotopic shifts measured on 7 bands allow the determination of the exact numbering of the vibrational levels of the excited 0 + -term. Furthermore molecular constants of both states involved could be determined. By means of this set of bands an empirical formula representing irregular vibrational terms of diatomic molecules is tested.
