Phys., 72, 4300 (1980). en_US dc.description Author Institution: Molecular Spectroscopy Division, National Bureau of Standards en_US dc.description.abstract Recently Baiocchi and $Klemperer^{1}$ have reported the microwave spectrum of $H_{2}CO-HF$ from a molecular beam electric resonance study. We have examined this system with a conventional waveguide Stark-modulated absoption cell in order to see if this species could be produced under thermal equilibrium conditions and to obtain further information about higher energy states which are not accessible in a cooled beam experiment. Both the cell and experimental conditions were similar to that described for the HF-$dimer^{2}$. With the aid of the molecular beam $data^{1}$ we have identified numerous a-type R-branch transitions up to J = 13 and K = 8. A combined analysis of the molecular beam spectrum and the present data requires inclusion of several $P^{6}$ terms in the Watson Hamiltonian in order to fit the higher K transitions. A much stronger spectrum was observed in the region searched ($\sim70 - 125$ GHZ). This has been analyzed and assigned to a reaction product of $H_{2}CO$ with HF, namely gauche-$CH_{2}FOH$. Both a- and b- type transitions are observed and occur as closely spaced doublets quite similar to gauche-$CH_{3}CH_{2}OH^{3}$. Further details of the measurements between 70 GHz and 125 GHz and analyses for each species will be presented. en_US dc.format.extent 136357 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title MILLIMETER WAVELENGTH STUDY OF THE $HF-H_{2}CO$ SYSTEM en_US dc.type article en_US
