Infrared absorption spectra of some simple hydrides

Understanding the Origins of Nucleophilic Hydride Reactivity of a Sodium Hydride–Iodide Composite

“…Attenuated total reflectance Fourier transform infrared (ATR‐FTIR) spectroscopy was undertaken on the composites, but no distinctive band was observed in the mid‐IR region, as expected for NaH . However, after the NaH–NaI sample had been employed for a reduction reaction, the ATR‐FTIR spectrum revealed the presence of CN − (2086 cm −1 ) in the bulk material as anticipated …”

Hydrogen Absorption/Desorption Mechanism in Potassium Alanate (KAlH4) and Enhancement by TiCl3 Doping

“…This vibration increases and then decreases in intensity as K 3 AlH 6 is produced and then decomposed into Al and KH at temperatures above 339 °C (see Supporting Information Figure S1). No vibration is expected for potassium hydride in the range of investigation . The stretching vibration of K 3 AlH 6 is at a lower frequency than that of lithium and sodium alanates (shifted by 180 cm −1 ). , This indicates a weaker Al−H bond strength in potassium alanate than in other alanates due to the influence of the cation.…”

Isotope effect in a Cu–H(D) system with hexagonal hydride phase

“…Additional confirmation of this finding could be extracted from studies of the photon absorption of copper hydride in an infrared region. Unfortunately, the majority of attempts to obtain infrared spectra of solid hydride have been unsuccessful [10,11]. The only positive result has been reported by Samodelov [12].…”
