Nuclear quadrupole hyperfine structure in 2_{1,2} ← 3_{0,3} and 1_{1,1} ← 2_{0,2} rotational transitions of CH_{2}^{35}Cl_{2} at 9.2 and 15.9 GHz, respectively, was measured with a newly constructed pulsed supersonic beam, cavity Fourier transform microwave spectrometer. All components of nuclear quadrupole splitting tensors of the chlorine nuclei in inertial and in principal quadrupole axes were determined. It is shown that in methylene halide molecules nuclear quadrupole information leads to a value for ∠(XCX) which is systematically larger than ∠(XCX) defined by the positions of the nuclei. Some novel features of the spectrometer are also described.
