“…The first and second overtones of the H-Kr stretching mode and the first overtone of the Kr-Cl stretch are predicted to be intense enough to be experimentally searched for, however, they were not observed in this work experimentally. [5], and the force constants for asymmetric stretches of KrF 2 and XeCl 2 are 2.59 N/cm and 1.32 N/cm [19,20], respectively. These data indicate a stronger Kr-F chemical bonding than Kr-Cl bonding in accordance with the electron localization studies of Berski and co-workers [21].…”

The Kr–Cl stretching vibration of HKrCl molecule is studied. The absorption shows Cl35 and Cl37 isotopic splitting due to natural abundance of the Cl isotopes. The observed Kr–Cl stretching vibrations of the HKrCl are at 253.1 (35Cl) and 248.3 cm−1 (37Cl). Experimentally, deuteration of the HKrCl does not cause a shift of the Kr–Cl stretching frequency. In addition to the Kr–Cl stretching mode, the bending mode of DKrCl is observed at 397.7 cm−1. The vibrational analysis suggests that the Kr–Cl bond shows some covalent character in addition to the ionic. Anharmonic ab initio calculations are employed to verify the vibrational properties of various isotopologues of HKrCl.

The synthesis of novel neutral rare‐gas‐containing molecules of type HXY, where × = Xe or Kr and Y is an electronegative atom or fragment, is discussed. The molecules are characterised experimentally by their vibrational spectra and computationally by extensive ab initio calculations. They are formed in low‐temperature rare‐gas solids from neutral reagents and their bonding consists of both covalent and ionic contributions. Our recent studies add to the previously known class of rare‐gas chemical bonds in neutral ground‐state molecules the new bonds Xe–H, Xe–I, Xe–Br, Xe–S, Kr–H, Kr–C, and Kr–Cl.
