Vibrational spectroscopy of Cu⁺(H₂)₄: about anharmonicity and fluxionality
The vibrational spectra of the copper(I) cation–dihydrogen complexes Cu⁺(H₂)₄, Cu⁺(D₂)₄ and Cu⁺(D₂)₃H₂ are studied using cryogenic ion trap vibrational spectroscopy in combination with quantum chemical calculations. The infrared photodissociation (IRPD) spectra (2500–7300 cm⁻¹) are assigned based on…
