The Ņ13, Ņ5 + Ņ15 and Ņ9 + Ņ15 Bands of 10B2H6



Walter J. Lafferty, J.- M. Flaud, H Berger, G Pawelke


The 5 m absorption region of an isotopically pure sample of diborane 10B2H6 has been analyzed using high resolution (0.0025 cm-1) Fourier transform spectra. A set of precise experimental rotational-vibrational energy levels has been obtained for three vibrational states, the 131 fundamental and two combination states, 51 151 and 91 151. These energy levels have been fitted using Hamiltonian matrices which take into account various interactions with nearby lying dark states. However, given the complexity of the resonance scheme and the number of interactions and dark states, it was not possible to reproduce the observed energy levels to within their experimental uncertainty, although considerably improved results have been obtained compared with previous studies.
