Accurate absolute frequency measurement of the S(2) transition in the fundamental band of H2 near 2.03 µm Series of spectra of the quadrupolar electric S(2) transition of H2 in the 1-0 band near 4917 cm-1 has been recorded at seven pressure values between 2 and 100 Torr. Comb-referenced cavity ring down spectroscopy technique (CR-CRDS) was used for the recordings of this very weak transition.
