Title: THE PURE ROTATIONAL FIR SPECTRA OF THE $HO_{2}$ RADICAL MEASURED BY FOURIER TRANSFORM SPECTROSCOPY
Creators: Von Bargen, Albrecht; Birk, M.; Wagner, G.
Issue Date: 1995
Abstract: Covering the spectral range $30 - 200 cm^{-1}$, spectra of the $HO_{2}$ radical have been recorded with a Fourier transform spectrometer (Bruker IFS 120HR) in combination with a White type absorption cell (absorption path length 72 m) at high resolution $(1/MOPD = 0.0017 cm^{-1})$. Because of the fast self-disproportion of $HO_{2}$ the measurements were performed under flow conditions. A line fitting program (INTBAT) was used to obtain the line positions and line strengths of more than 250 b-type transitions up to $N^{\prime\prime} = 22$ and $K^{\prime\prime} = 4$. Utilizing an A-reduced Hamiltonian in a parity conserving basis set the molecular parameters were determined by means of a non linear least squares fitting program. The results of the fit and a discussion of the relative line strengths will be presented.
