The 101→ O00 and 313→3 12 transitions of HCOOD were measured using a beam maser spectrometer with 4 kHz resolution. The measurements of three completely resolved components for each of these transitions allowed an unambiguous assignment of the spectrum. The quadrupole coupling strength in the O-D bond direction is eq zzQ = 272 ±3 kHz with an asymmetry η = - 0.075 ± 0.010. Analysis of previous data on DCOOH yields a deuterium quadrupole coupling strength along the D-C bond direction of eqzzQ = 166 kHz.
