MICROWAVE SPECTRUM OF FORMYL FLUORIDE

Summary The microwave spectrum of Formyl Fluoride has been investigated in the range of frequency from 8·200 to 48·000 Mc/s. The measurements have been made by a Stark modulated spectrograph. Seven absorption lines are assigned as belonging to transitions of “ b ” type, generally with high J, and to transitions of “ a ” type. The asymmetry parameter and the rotational constants are determined as a first approach to the structure of the molecule.
