Abstract
Microwave and radio frequency spectra of 132XeH35Cl are measured by molecular beam electric resonance spectroscopy. The spectroscopic constants determined for this complex are B=989.262 (5) Mhz, D J =3.84 (32) kHz, (e q Q) a 35Cl=−34.640 (20) MHz, μ a =1.0901 (30) D. Only a single vibrational level, with zero angular momentum along the heavy atom axis, has been observed. The results are interpreted in terms of a linear complex with large amplitude oscillation. The structure is assumed to have atomic arrangement XeHCl. The average Xe–Cl distance is 4.258 Å. The average angle of the HCl subunit with the heavy atom axis is 34.8°. The stretching frequency of the weak bond is 33.5 cm−1.Keywords
