 Title: THE FAR INFRARED SPECTRUM OF $H_{2}O_{2}^{*}$ Creators: Hunt, R. H.; Peters, C. W. Issue Date: 1961 Abstract: The absorption of $H_{2}O_{2}$ between 15 nd $150 cm^{-1}$ has been examined with a grating spectrometer (0.3 to $0.5 cm^{-1}$ resolution). The interpretation of most of the strong lines (a series of doublets) is consistent with that of Massey and $Bianco^{1}$ for the microwave spectrum: that $H_{2}O_{2}$ is a nearly symmetric top with the K levels split by the hindered rotation potential barrier. The observed doublets aries from the transitions $\Delta K = 1$ and $\Delta J = 0$, and yield values of $9.19 cm^{-1}$ for (A--B). and $11.43 cm^{-1}$ for the average splitting of the K levels.
