Tables of N2O absorption lines for the calibration of tunable infrared lasers from 522 cm−1 to 657 cm−1 and from 1115 cm−1 to 1340 cm−1

Abstract

Data from the literature has been critically selected and refitted by least squares to provide accurate vibrational band centers and rotational constants for three bands of N₂O. The line positions of the bands have been calculated from the constants of the fits to provide accurate absorption line positions to serve as wavelength standards in the regions of 522 cm⁻¹ to 657 cm⁻¹ and from 1115 cm⁻¹ to 1340 cm⁻¹ in the infrared.
