  The electronic spectrum of the GeH₃ radical

  摘要：

  The germyl (GeH3) radical has been observed by resonance enhanced multiphoton ionization (REMPI) spectroscopy in the region of 370–430 nm. The spectrum arises from two-photon resonances with the 5p 2A″2 (D3h) Rydberg state that possesses an origin at 419.1 nm (ν0–0 =47 705 cm−1). A vibrational progression of 756 cm−1 was assigned to the ‘‘umbrella’’ mode, ν2. The observed X̃ 2A1 (C3v) v″2=2 to v″2=0 vibrational interval is 663 cm−1 which leads to an estimated barrier to inversion of 1530 cm−1.

  and Pb atoms have been co-deposited with pure hydrogen at 3.5 K to form the group 14 hydrides. The initial SiH(2) product reacts completely to SiH(4), whereas substantial proportions of GeH(2), SnH(2), and PbH(2) are trapped in solid hydrogen. Further hydrogen atom reactions form the trihydride radicals and tetrahydrides of Ge, Sn, and Pb. The observation of PbH(4) at 1815 cm(-)(1) and PbD(4) at 1302

• GeHx (x=0–3) and GenHx (n=2–7) in flash pyrolysis of GeH4
  作者：Steven D Chambreau、Jingsong Zhang

  DOI：10.1016/s0009-2614(01)01385-9

  日期：2002.1

  Gas-phase thermal decomposition of germane, GcH(4), has been studied using a flash pyrolysis technique (similar to20 mus reaction time), coupled with a vacuum-ultraviolet (VUV) photoionization time-of-flight mass spectrometer (TOFMS). Pyrolysis temperatures ranged from 685 to 1500 K, and resulted in the formation of GeH2 above 900 K and GeHx (x = 0, 1, 3) above 1100 K. In addition, Ge-n (n = 2-7) and a small amount of highly unsaturated hydrogenated GenHx (n = 2-7) clusters were observed above 1100 K. (C) 2002 Elsevier Science B.V. All rights reserved.
• Free radicals formed by reaction of germane with hydrogen atoms in xenon matrix at very low temperatures

  日期：1987.5

  The radicals formed by the reaction of GeH4 with H in the Xe matrix were investigated by electron spin resonance (ESR) spectroscopy at very low temperatures. The radicals observed were identified as GeH3 and GeH5. The newly observed radical GeH5 is considered as the intermediate of the reaction H+GeH4→H2+GeH3. The ESR parameters of these radicals were determined by numerical deconvolution of the observed spectra.
