摘要: The radio frequency and microwave spectra of K = 0 states ArHCl ArDCl have been measured by molecular beam electric resonance spectroscopy. rotational hyperfine structure constants for the lowest vibrational state four isotopic species are ArH35 ClArD35 ClB (B+C)/2 1.678511 (5)GHzB − 2DJ 1.657596 (10)GHzDJ=20.33 (20)kHz(eqQ)aC1 −36.250 (20)MHz(eqQ)a=−23.027(10)MHz(eqQ)aD +102.3 (50)kHzμa=0.81144(10)Dμa=1.00355(70)D ArH37 ClArD37 ClB 1.631566 1.611876 (10)GHz Only has observed. molecule is extremely nonrigid. average Ar–Cl distance 4.006 A in 4.025 ArDCl. Ar–Cl–H angle acute amplitude zero point bending large. near 45°, while Ar–Cl–D 34°. Ar–HCl bond stretching computed to be 32.2 cm−1 from observed centrifugal distortion constant.
