Abstract

Techniques are described for drift compensation and scan calibration of a visible-to-infrared difference-frequency converter enabling high-resolution molecular spectra to be recorded with a precision and reproducibility of 5 × 10<sup>-4</sup> cm<sup>-1</sup>. The capabilities of the spectrometer are illustrated by scans of the tetrahedral fine structure in the <i>V</i><sub>3</sub> band of methane under low pressure, Doppler-limited and atmospheric pressure, collision-broadened conditions.
