ResumoThe rotational spectrum of HDO in the ground vibrational state has been studied in the millimeter and submillimeter microwave region. Twenty-one previously unreported transitions have been measured and assigned. These data have been combined with previous measurements on HDO for a centrifugal distortion analysis based entirely on microwave measurements. In the analysis distortion effects through P10 are included, although only a partial set of terms in P8 and P10 is found to be necessary. The results for the rotational constants, quartic and sextic distortion constants are (in megacycles per second): =701 931.50 ± 0.22, BA=272 912.60 ± 0.11, C=192 055.25 ± 0.10, ΔJ= 10.8375 ± 0.0058, ΔJK=34.208 ± 0.036, ΔK=377.078 ± 0.026, δJ=3.6471 ± 0.0014, δK=63.087 ± 0.035, HJ=1.128 × 10−3 ± 0.099 × 10−3, HJK=7.344 × 10−2 ± 0.092 × 10−2, HJK=−2.740 × 10−1 ± 0.022 × 10−1, HK=1.4651 × 100 ± 0.0027 × 100, hJ=6.546 × 10−4 ± 0.150 × 10−4, hJK=3.096 × 10−2 ± 0.037 × 10−2, and hK=5.549 × 10−1± 0.053 × 10−1.
