  Pure rotational spectrum of Kr...HCl in the excited state (10⁰0) observed with a glow‐discharge source in a pulsed‐nozzle Fourier‐transform microwave spectrometer

  摘要：

  The pure rotational spectra of the four isotopomers 84Kr...H 35Cl, 84Kr...H 37Cl, 86Kr...H 35Cl, and 84Kr...D 35Cl of the van der Waals complex of krypton and hydrogen chloride have been observed in the vibrationally excited state (1000) by incorporating a pulsed glow-discharge source of excited-state molecules into a conventional pulsed-nozzle Fourier-transform microwave spectrometer. The rotational constant B1, the centrifugal distortion constant D1, and the Cl nuclear quadrupole coupling constant χ1(Cl) are reported for each isotopomer. The time of flight of the (1000) Kr...HCl molecules between the region of vibrational excitation and the detection region of the spectrometer indicates that the vibrational predissociative lifetime of the state (1000) is τ≥400 μs. Molecular properties of (1000) Kr...HCl determined from the observed spectroscopic constants are compared with those previously available for the ground state.

  A new method of observing the rotational transitions of weak molecular complexes by combining the techniques of microwave Fourier transform spectroscopy, a Fabry–Perot cavity, and a pulsed nozzle source of molecules is described. High resolution and good sensitivity are achieved. Twelve isotopic species of the KrHCl molecule involving all combinations of the 86Kr, 84Kr, 82Kr, H, D, 35Cl, and 37Cl isotopes are assigned and the rotational constants, Cl nuclear quadrupole coupling constants, and centrifugal distortion constants are all given. The molecular structure indicates a linear equilibrium structure with the H(D) atom between the Kr and Cl atoms. However, the inverse moments of inertia measured here indicate large amplitude vibrations of the H(D) atom relative to the Kr–Cl internuclear line. Estimates of the Kr–Cl stretching frequency and force constants, which show considerable dependence on the isotopic species, are also given. Bending frequencies and force constants are also given.
