THE PURE ROTATIONAL ABSORPTION SPECTRUM OF FORMALDEHYDE

Abstract

“The $CH_{2} O$ absorption spectrum between about $20 cm^{-1}$ and $80 cm^{-1}$ was recorded with the far infrared spectrograph at the Ohio State University. Asymmetric rigid rotator energy term values F(Jr) weere calculated using the rotational constants reported by R. B. Lawrance and M. W. P. Strandberg in the Physical Review 83, 363 (1951). The comparison of the observed and the calculated spectra shows excellent agreement, both in wavelength positions, and in intensities.”
