Abstract

The 1₀₁-0₀₀ rotational transition was observed in HCOOH, HCOOD, and DCOOH using a maser spectrometer. Quadrupole hyperfine structure was completely resolved in HCOOD and DCOOH. The measured quadrupole coupling strength along the OD-bond direction was eqQ=391 kHz and HCOOD and eqQ= 249 kHz along the DC-bond direction in DCOOH. These coupling constants and the deuterium quadrupole coupling in NH₂D are compared with the corresponding force constants and the results are in fairly good agreement with the theory of Salem.
