Raman Spectrum of Hydrogen Peroxide

Nature volume 127, page 406 (14 March 1931) | Download Citation



THE Raman spectrum of hydrogen peroxide (Merck's perhydrol 30 per cent solution in water) has been photographed. The prominent feature of the spectrum is the presence of a sharp Raman frequency of 875 accompanied by a weak component at 903. The low value of the frequencies suggests that they arise from the oxygen atoms, and as such may be compared with the O2 oscillation frequency 1552 obtained by McLennan (Trans. Farad. Soc., 25, 798 ; 1929). The large difference between the two values is indicative of the fact that the oxygen atoms in hydrogen peroxide (H2O2) and oxygen (O2) molecules respectively are bound differently. Besides the above two frequencies, there appear other bands which are loss intense and sharp, the origin of which is under investigation. A detailed discussion of the results obtained in relation to the structure of the molecule will appear elsewhere.
