High-resolution cavity ring-down spectroscopy measurements of blended H2O transitions

We probed four closely spaced rovibrational water vapor absorption transitions near [(n)\tilde] =7100 cm-1 using frequency-stabilized cavity ring-down spectroscopy. Room-temperature spectra were acquired for pure water vapor in the Doppler limit and for mixtures containing Delta #~6.6 Delta *mmolmol...

Description
Summary:We probed four closely spaced rovibrational water vapor absorption transitions near [(n)\tilde] =7100 cm-1 using frequency-stabilized cavity ring-down spectroscopy. Room-temperature spectra were acquired for pure water vapor in the Doppler limit and for mixtures containing Delta #~6.6 Delta *mmolmol-1 of water vapor in N2 at total gas pressures ranging from 6.5 kPa to 53 kPa. By measuring Lamb dips for each transition, we demonstrated a resolution of 50 kHz and determined relative transition frequencies with an uncertainty
