摘      要：The microwave spectrum of C 4 O 2 Cl 2 (1,2-dichlorocyclobuten-3,4-dione) has been investigated for both the C 4 O 2 35 Cl 2 and the C 4 O 2 35 Cl 37 Cl isotopomers. The spectrum of the latter has been studied in greater detail because a number of μ b rotational transitions were measured with the radiofrequency-microwave double-resonance technique by radiofrequency pumping of some K −1 doublets. This pumping has been made possible since a small μ a dipole moment component appears owing to the asymmetric isotopic substitution.
