Abstract
A hyperfine structure of the 4 1,4 →4 1,3 transition in the microwave spectrum of formaldehyde has been observed. The observed hyperfine features are mainly explained in terms of the interaction of the magnetic moments of the protons with the moleculer rotational magnetic field. The main absorption lines were composed of three strong lines with total quantum numbers F =3, 4 and 5 respectively. The determined splitting frequency between the F =5 and the F =3 lines was 188±15 kc. For a detailed explanation of this value, further information on electronic and magnetic properties of this molecule is required.
