✦ Synopsis

Magnetic rotation spectra of the 4; and 42 bands of the A 'AZ-z tAI system of formaldehyde+ have been photo-gapBed under high resqlution Assignments of the magnetic rotation tines have been made and the excited state rotationat kvels invoked in sin&t-tripkt perturbations have been identified. bkgnetic optica sctirity in the x 'AZ-% 'A, system of fonnaId+hyde w3s fust observed by Kusch and Loomis in 1939 [ 1 j_ The strong activity found near 3260 _& for HzCO has been esplained in terms ofsinglet-tripfet perturbations, between the Z24t IeveI of the singiet state and two or more vibrational kveb of the underIying$ 3& state !2-5J_ Magneticzd-Iy sensitive rotational IrveIs w&e identified by Brand and coIIe3gues f2-41 using Zeemzu~ studies and by Birss et al_ [5] using I&J1 resolution magtetic rotation spectra. hhgnetic rrctivitz has zdso been found in
