Abstract
A FRACTION of the product of fluorination of cyanogen, in which fluorine cyanide was detected by infra-red spectroscopy1, has now been shown to absorb in the microwave regions of 21,000, 42,000 and 63,000 Mc./s. The absorptions occur in the frequency-ranges expected from the resolved rotational structure of the infra-red band, ν3, centred on 1,077 cm.−1. Their Stark effects and nuclear quadrupole splittings are those expected for J = 0 → 1, 1 → 2 and 2 → 3 transitions in the linear molecule, FC14N. Spectra due to molecules with one quantum of vibrational energy in the degenerate bending mode (ν2) have also been measured.
