For the dideuterated species, the energy spacing was found to be $86448.12 \pm$ 0.53 MHz, and direct transitions between the two states have been observed. For the O-d monodeuterated species, the energy spacing was $87402 \pm$ 131 MHz and for the dideuterated doubly substituted $O^{18}$ species, the energy spacing $81405 \pm$ 58 MHz. The implications of these results with respect to the potential function will be discussed and comparisons with theoretical calculations will be made. Progress on the analysis of perturbations at higher J levels for the normal species will be reported. en_US dc.format.extent 174913 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title THE HYDROGEN BOND POTENTIAL FUNCTION OF MALON-ALDEHYDE STUDIED BY MICROWAVE SPECTROSCOPY en_US dc.type article en_US
