The J = 2-1 and 1-0 transitions in both the ground and first excited vibrational states have been measured with a cavity pulsed jet Fourier-transform microwave spectrometer. An improved equilibrium internuclear distance (r(e)) has been obtained. Hyperfine structure in the rotational spectrum of AsP has been resolved and has led to the first determinations of the As nuclear quadrupole coupling constant and both nuclear spin-rotation constants. The data enable the electronic structure of AsP to be compared with those of other mixed Group 15 diatomic molecules. (c) 2006 Elsevier Inc.

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 similar to2.594 and similar to1.957 Angstrom respectively have been determined. A small centrifugal distortion constant (similar to0.3 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 similar to113 cm(-1) and similar to32 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.
