Deuterium quadrupole coupling in formyl fluoride

Research output: Contribution to journalArticlepeer-review

8 Scopus citations


The 101-000 rotational transition in HFCO and DFCO was recorded with a beam maser spectrometer. Hyperfine structure due to the deuterium quadrupole coupling was observed for DFCO. Analysis of the spectrum yielded the deuterium quadrupole coupling strength along the D-C bond direction of eqQ=205.± 4. kHz. This rotational transition had not been reported previously for DFCO. A comparison of deuterium quadrupole coupling strengths with force constants along the H-C bond is made according to the theory of Salem.
