  ESR of Free Radicals Trapped in Inert Matrices at Low Temperature: CH₃, SiH₃, GeH₃, and SnH₃

  摘要：

  The free radicals CH3, SiH3, GeH3, and SnH3 have been produced in a krypton matrix at 4.2°K by γ irradiation of the matrix containing dilute concentrations of CH4, SiH4, GeH4, and SnH4. The electron spin resonances indicate free or restricted rotation for all the radicals in the matrix. Observed anisotropies in g show that SiH3, GeH3, and SnH3execute restricted rotation about an axis perpendicular to the symmetry axis. From the observed values for the rotating radicals, the axially symmetric principal g values for the static radicals are derived as follows: for SiH3, g∥ = 2.003, g⊥ = 2.007; for GeH3, g∥ = 2.003, g⊥ = 2.017; for SnH3, g∥ = 2.003, g⊥ = 2.025. Hyperfine structure caused by 29Si is observed for SiH3 with isotropic coupling constant Af = 266 G and anisotropic coupling Aμ = 24 G. These couplings reveal 22% scharacter in the orbital of the unpaired electron, which indicates that the radical is nonplanar with bond angles of 110.6°. Probably GeH3 and SnH3 are also nonplanar. The magnitudes of the isotropic proton couplings are: 23, 8.1, 15, and 26 G, respectively, for CH3, SiH3, GeH3, and SnH3. The coupling of SiH3 is probably negative like that for CH3, but that of GeH3 and of SnH3 may be positive.

  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

  激光烧蚀的 Si、Ge、Sn 和 Pb 原子与纯氢在 3.5 K 下共沉积，形成 14 族氢化物。最初的 SiH(2) 产品与 SiH(4) 完全反应，而 GeH(2)、SnH(2) 和 PbH(2) 的很大比例被困在固体氢中。进一步的氢原子反应形成 Ge、Sn 和 Pb 的三氢化物自由基和四氢化物。1815 cm(-)(1) 处的 PbH(4) 和 1302 cm(-)(1) 处的 PbD(4) 的观察结果与这些不稳定的甲烷四氢化物类似物的量子化学计算的预测一致。此外，新的吸收被观察到 Pb(2)H(2) 和 Pb(2)H(4)，它们具有基于量子化学计算的双桥结构。
