Rotational and quadrupole coupling constants have been obtained in each case. The rotational constants are, for $Cl^{35} C_{6} H_{4}CHO$, A = 5058.25, B = 691.9960 and C = 608.8328 and for $Cl^{37} C_{6} H_{4}CHO$, A = 4961.29, B = 677.0989 and C = 595.9180. All values being in MHz. Some preliminary work has also been done to identify the ground state rotational spectrum for p-fluorobenzaldehyde. We shall report the structure for the benzaldehyde framework as determined from the effective principal moments of inertia of these three molecules and those for $C_{6} H_{5}CHO$ and $C_{6} H_{5}CDO$. en_US dc.format.extent 89524 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title MICROWAVE SPECTRUM OF p-CHLORO AND p-FLUORO BENZALDE-HYDES en_US dc.type article en_US
