The Stark and Zeeman effects of $ClO2$ have been measured and interpreted. The dipole moment of $ClO2$ as found from the Stark effect measurements is $1.785\pm .01$ Debye. Appreciable higher order effects arising from the hyperfine structure had to be considered in this calculation. The Zeeman effect can be predicted simply by the interaction of the free electron with the magnetic field, and is found to be in good agreement with the observed spectra. The anisotropic components of the g factor are too small ($\sim 1\%$) to be measured reliably with low magnetic fields.
