摘要：

The ground-state rotational spectra of four isotopomers of the complex OC...ClF have been observed by using a fast-mixing nozzle in a pulsed-nozzle, Fourier-transform microwave spectrometer. The spectrum of the reaction product carbonyl chloride fluoride was detected but its intensity indicated that the extent of the reaction was small. The observed spectroscopic constants B-o, D-J, chi(aa)(Cl) and M(bb)(Cl) were interpreted to show that the pre-chemical complex has the nuclei collinear in the order OC...ClF, with r(C...Cl) = 2.770(3) Angstrom and the intermolecular stretching force constant k(sigma) = 7.03(3) N m(-1). There is only a minor electric charge redistribution within ClF on complex formation.
