Detection and analysis of new bands of 16O3 by CRDS between 6500 and 7300 cm−1

► High sensitivity CW-Cavity Ring Down Spectroscopy is used. ► The spectral region between 7065 and 7300 cm−1 is recorded. ► The absorption of 16O3 molecule is analyzed. ► Two A-type bands are fully assigned. ► Hamiltonian and transition moment parameters are derived.
