The ground state infrared spectra of four diatomic deuterides (GaD, InD, TlD, AgD) and the determination of mass‐independent molecular parameters
摘要:
The infrared spectra of two isotopic forms of the monodeuterides of the metals gallium, indium, thallium, and silver have been measured in their ground electronic state (1Σ) in the gas phase using a diode laser spectrometer. The analysis of the experimental data was carried out in two ways: (a) a complete set of Dunham parameters was determined for each isotopic species independently and (b) all the available data over both deuterated and protonated species of a particular compound were simultaneously fitted to obtain a set of mass-independent parameters. Mass scaling coefficients, which take into account effects arising from a breakdown of the Born–Oppenheimer approximation, were determined for the hydrogen atom.

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 InH3. Annealing provides evidence for In2H6 and ultimately the sharp absorption bands are replaced with a broad IR band centered at 1460 cm−1 assigned to solid indane (InH3)n [see Equation].$\vcenter\openup.5em\halign$#$\cr \rm InH}_3}\rightarrow 1\over 2}\rm In}_2}\rm H}_6}\rightarrow 1\over n}(\rm InH}_3})_n}\hfill\cr}}}$
