Abstract : The infrared spectrum of the rare isotopologue 14C16O2 has been investigated in the range 2190-2250 cm-1 with a frequency comb-referenced cavity ring-down spectrometer. Thirty-three ro-vibrational transitions of the ν3 fundamental band have been detected. Their absolute frequency was measured with an relative uncertainty ranging from 7.1×10-8 to 1.1×10-8. 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.
