We demonstrate the potential capability of the cavity-enhanced spectrometer for molecular spectroscopy. We take the 1.65-/spl mu/m spectrum of methyl iodine (CH/sub 3/I) as a sample for the following reasons. First, the global spectrum with a Doppler-limited resolution has been recorded, and has not been analyzed yet. Second, there are a lot of absorption lines extending in a wide wavelength range, and the hyperfine structures and Q-branch lines are overlapped in the Doppler-limited resolution spectrum and can be resolved by the present spectrometer.
