Abstract

The microwave spectrum of KrAgF has been assigned between 8-18 GHz, using a cavity pulsed-jet Fourier transform microwave spectrometer. The structure of the molecule has been calculated from the measured rotational constants of four isotopomers. Values for the Kr-Ag and Ag-F bond lengths of ∼2.594 and ∼1.957 Å respectively have been determined. A small centrifugal distortion constant (∼0.3 kHz) indicates that the molecule is comparatively rigid. The stretching frequency and dissociation energy of the Kr-Ag bond have been subjected to ab initio calculation at the MP2 level, yieling results of ∼113 cm^-1 and ∼32 kJ mol^-1 respectively. A Mulliken orbital population analysis suggests that the Kr-Ag bond is weakly covalent in nature. All parameters are found to be consistent with trends established for ArMX and KrMX species.
