NIST Wavenumbers for Calibration of IR Spectrometers - SRD 118

Published by National Institute of Standards and Technology | National Institute of Standards and Technology | Catalog Last Checked: August 03, 2026 at 03:49 AM | Dataset Last Updated: April 01, 1998
Wavenumber Calibration Tables from Heterodyne Frequency Measurements contains tables of gas-phase infrared transition wavenumbers and their spectroscopic assignments that are appropriate for calibrating high-spectral-resolution infrared spectrometers. The calibration lines for carbonyl sulfide (OCS), nitrous oxide (N2O), nitric oxide (NO), carbonyl sulfide (CS2), and carbon monoxide (CO) collectively extend from approximately 486 wavenumber (cm-1) to 4355 wavenumbers (cm-1) in the infrared. The bibliography and spectral atlas are current through November 1994. The bibliography covers a range of high-resolution spectroscopic studies on the calibration molecules listed above, including pressure broadening studies.
