The microwave spectrum of (E)-benzaldehyde oxime, C6H5-CH=NOH and C6H5-CH=NOD, has been observed in the frequency range from 26.5 to 40.0 GHz. The spectrum of the ground vibrational state was assigned and fitted to the Watson's A-reduced Hamiltonian to obtain these rotational and centrifugal distortion constants: A = 5183.13(29) MHz, B = 895.367(3) MHz, C = 763.819(3) MHz, ΔJ = 0.019(3) kHz, and ΔJK = 0.204(7) kHz for the normal species, and A = 5158.4(23) MHz, B = 869.44(2) MHz, C = 744.34(2) MHz, ΔJ = 0.023(2) kHz, and ΔJK = 0.193(7) kHz for the deuterated species. The values of the ΔI (=Ic - Ia - Ib) obtained for the normal and deuterated species were -0.295(6) and -0.28(5) a.m.u. A2, respectively. The molecular conformation of this molecule was a planar one in which the values of the dihedral angles, CCNO and CNOH, were almost 180° and 180°, respectively.
