On the Infrared Spectrum of Hydrogen Peroxide Matrix-Isolation Studies of the System H2O2:N2 (II)

Matrix-isolation spectra of the system H2O2:N2 were obtained in the region 4000–300 cm—1 at 4.2°K. Spectra taken in this manner are free of complications due to association, over-all rotation, etc. The most unusual feature of these spectra is the band system at 385 and 350 cm—1 in the torsional region. This main band at 385 cm—1 is exceedingly broad for a matrix spectrum. These bands have been assigned to the n=0→1 and 1→2 torsional transitions.
