摘要：

A high-resolution cavity ring-down spectrometer has been constructed employing a tuneable cw diode lasing around 1300 nm (bandwidth and frequency stability better than 1 MHz) and a frequency-matched cavity. The performance of the spectrometer has been tested on the Sigma-Sigma combination band v(1) + 3v(3) of N-14(2) O-16 around 7780 cm(-1) at Doppler-limited resolution, for which we report integrated absorption cross-sections, line positions and detection limits. CH-chromophore absorptions of (CHCl3)-C-12 between 7700 and 7750 cm(-1) have also been observed, in agreement with previous predictions with an effective Hamiltonian based on a Fermi-resonance polyad model.
