Infrared Spectra of Indium Hydrides in Solid Hydrogen and of Solid Indane

One little indium : Reactions of laser‐ablated indium atoms with pure hydrogen give sharp IR absorptions corresponding to InH intermediate species. Irradiation at 193 nm maximizes further reaction to give the indane monomer InH 3 . Annealing provides evidence for In 2 H 6 and ultimately the sharp absorption bands are replaced with a broad IR band centered at 1460 cm −1 assigned to solid indane (InH 3 ) n [see Equation]. .5em#InH₃→ 1 2 In₂ H₆→ 1 n( InH₃)ₙ
