Infrared Spectrum of Stannane

Hydrogen mediated transport of Sn to Ru film surface

“…5͒ that ·H prefers to bind Ru and does not adsorb on Sn although one could expect an opposite preference just based on the Sn-H bond dissociation energy ͑264Ϯ 17 kJ/ mol or 2.74 eV͒, 35,75 which exceeds the strength of Ru-H bond ͑223Ϯ 15 kJ/ mol or 2.31 eV͒. 35 In the earlier study of atomic H adsorption on the ͑ͱ3 ϫ ͱ 3͒-R30°Sn/Pt͑111͒, 76 the hydrogen was also asserted to bind only to Pt atoms but not to Sn.…”

Vacuum-Ultraviolet Photodecomposition of Stannane

“…On the other hand, we note that the primary photodissociation can lead to quantum yields as high as 6. On the basis of published enthalpies of formation of Sn, SnH 4 , and Sn 2 H 6 and D (H 3 Sn−H), we have estimated, by bond energy considerations, the following heats of reaction: We note that both eqs 8 and 9 are energetically feasible for 147-nm photons (195 kcal/einstein); however, eq 9 is not energetically possible for 193-nm photons (148 kcal/einstein), so that eq 8 is quite reasonable, as proposed, for the photodecomposition at this latter wavelength. We note also that the primary photodissociations in SiH 4 and GeH 4 analogous to eq 9 are not energetically feasible with 147-nm radiation, while those analogous to eq 8 are.…”

The Covalent Hydrides and Hydrides of the Groups V to VIII Transition Metals

“…However, data based on appearance potential measurements fixed the lower limit for the ΔΗ° of this hydride at 25°C as 59.7 kcal/mole. 273 Stannane is presumably tetrahedral 275 with a tin-to-hydrogen bond distance of 1.76 A. sures. The dissociation energy of the PbH molecule, which is known spectroscopically, is 41.5 ± 4.5 kcal/mole.…”
