Slivnik and co-workers °° have described a photosynthetic route for the preparation of 100 g quantities of O2F2 which involves the near-u.v. irradiation of a mixture of O2 and F2 at — 196°C. 

The electronic absorption spectra of molecular O2F2 and of the radical O2F have been measured in liquid Ar and in other solvents in the region 190—600 nm/° An analysis of the data concerning the nature of the unstable violet and blue compounds that were first reported in 1962 by Streng and Grosse suggests that the colours are due to oxygen fluoride radicals, such as O2F, and not to chlorine oxide fluorides. Thus, it has now been shown that intensely coloured species are formed by O2 salts in liquid HF these species show the same characteristics as the violet and blue compounds . 

Laser Raman spectra have been obtained for CF3OF and CF3OCI for the first time, and modified assignments of the vibrational spectra have been proposed. The e.s.r. spectra of ClOCr and FCIO have been remeasured and analysed in detail by Eachus and Symons. The chemistry of dichlorine monoxide has been reviewed by Renard and Bloker their review examines in particular the chemistry of this gas relating to the wood-pulp and textile industries. 

Tantot and Bougon have prepared KBr02F2 by reaction (15) the salt of the BrFj + KBr03 KBrOjFj + BrFj + (15)
