Irion, M. Seitz, K.L. Kompa Title: The UV spectra of tetraborane(10) and pentaborane(9) in the gas phase Journal/Source: J. Mol. Spectr., 118 (1), 64-69, (1986); http://dx.doi.org/10.1016/0022-2852(86)90223-7 Data: diagram, table Energy/Wavelength range: ~ 187 - 230 nm Resolution: Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: gas pH: Comments: The UV spectra of gaseous B4H10 and B5H9 are measured down to about 187 nm and are compared to the already known spectrum of B2H6. All the spectra are completely continuous, which suggests repulsive excited states. Author to whom correspondence should be addressed: (e-mail address):
