 Title: THE INFRARED SPECTRA OF GASEOUS AND SOLID $Ge_{2}H_{6}$ Creators: Dows, David A.; Hexter, R. M. Issue Date: 1955 Publisher: Ohio State University Abstract: The infrared spectra of gaseous and solid $Ge_{2}H_{6}$ have been studied in the region 400-4000 cm$^{-1}$. In the gas phase, the $A_{2{u}}$ fundamental frequencies are 2078 and $755 cm^{-1}$, and the $E_{u}$ frequencies are 2114, 899, and $407 cm^{-1}$. A tentative assignment of observed combination bands gives values for several other fundamental frequencies, including the Ge-Ge stretching frequency ($226 cm^{-1}$) and the torsional frequency ($145 cm^{-1}$). From the latter frequency, a barrier to internal rotation of about 1200 calories is estimated. The rotational structure of the perpendicular band $\nu_{e}$ has been partially resolved, giving information connecting the structure of the molecule with the coriolis constant for this vibration. The spectrum of the solid, obtained at $90^\circ K$ shows bands which are apparently derived from the $E_{g}$ fundamentals, indicating that the site symmetry is $D_{3}$ or lower. Small splittings of certain other bands are observed. Description: Author Institution: Department of Chemistry, Cornell University URI: http://hdl.handle.net/1811/7423 Other Identifiers: 1955-M-9
