Abstract
Rotational spectra of two isotopomers of the 2,5-dihydrofuran/ClF comp lex were observed by using the fast-mixing nozzle/Balle-Flygare spectr ometer combination. The complex has C-s symmetry and a pyramidal confi guration at oxygen. The angle between the (ClF)-Cl-35 axis (z) and the a-axis, alpha(az) = 17.95(3)degrees, was determined from the Cl nucle ar quadrupole coupling tenser. The geometry r(O...Cl)= 2.422(5) Angstr om, phi = 127.0(3)degrees and theta = 1.99(15)degrees is established w hen rotational constants are fitted under the constraints of unperturb ed monomers and alpha(az) = 17.95(3)degrees. The configurations phi at O and the nonlinearities theta of the B...ClF/B...HCl systems are com pared for B = 2,5-dihydrofuran and oxirane. (C) 1997 Elsevier Science B.V.
