摘要：

The rotational spectra of three isotopic species C(4)H(6)O ... H(35)Cl, C(4)H(6)O ... H(37)Cl and C(4)H(6)O ... D(35)Cl of the hydrogen-bonded dimer formed by cyclobutanone and hydrogen chloride have been studied by means of microwave spectroscopy in a supersonic jet. Rotational constants, centrifugal distortion constants and Cl-nuclear quadrupole coupling parameters have been determined for the ground state and for a vibrationally excited state attributable to the ring-puckering motion of the cyclobutanone subunit. The spectroscopic constants have been interpreted in terms of a C(s) symmetry in which the monomers are coplanar with: r(O ... H) = 1.86(3) Angstrom, angle(C=O ... H) = 112.3(7)degrees and a deviation theta of the O ... H-Cl nuclei from collinearity of 13.1(6)degrees. (C) 2000 Elsevier Science B.V. All rights reserved.
