    Research output: Contribution to journalArticlepeer-review


    A femto-OPO laser fitted to a high-finesse cavity and a Fourier transform spectrometer to perform femto-FT-CEAS (for femto-Fourier transform-cavity enhanced spectroscopy) was used to record high overtones of carbon disulfide with a minimal rms equivalent absorption coefficient of 1.2 × 10 cm Hz per spectral element. New vibrational states are reported for CS and CSS and new or improved rotational constants are obtained, for the v2 = 303, 223, 014 and 403 states in CS and 303 state in SCS.
