The microwave spectrum of 2-pyridinecarbaldehyde has been observed in the region 8–22 GHz. The rotational constants of the ground state are <I>A</I>=5362.52±2.19 MHz, <I>B</I>=1620.07±0.03 MHz, and <I>C</I>=1244.42±0.03 MHz and the inertia defect is −0.075 amu·Å<SUP>2</SUP>. This value demonstrates that the molecule is planar in its equilibrium position. The total dipole moment is 3.56±0.07 D, the components of which are μ<SUB>a</SUB>=3.48±0.05 D and μ<SUB>b</SUB>=0.76±0.08 D. From these facts it is concluded that the conformation of the molecule is of the O–N <I>s-trans</I> form. The rotational constants of the five vibrationally-excited states have also been determined.
