The infrared spectrum of the rare isotopologue 14C 16O2 has been investigated in the range 2190–2250 cm1 with a frequency-comb-referenced cavity ring-down spectrometer. Thirty-three ro-vibrational transitions of the 3 fundamental band have been detected. Their absolute frequency was measured with a relative uncertainty ranging from 7:1108 to 1:1108 . The experimental frequencies were fitted to the conventional Hamiltonian of a linear molecule and a new set of spectroscopic parameters for the fundamental vibrational state has been improved for this species.

Abstract

The infrared spectrum of the rare isotopologue 14C 16O2 has been investigated in the range 2190–2250 cm1 with a frequency-comb-referenced cavity ring-down spectrometer. Thirty-three ro-vibrational transitions of the 3 fundamental band have been detected. Their absolute frequency was measured with a relative uncertainty ranging from 7:1108 to 1:1108 . The experimental frequencies were fitted to the conventional Hamiltonian of a linear molecule and a new set of spectroscopic parameters for the fundamental vibrational state has been improved for this species.
