Calculation of accurate CO2 laser transition frequencies and their standard deviations

Abstract: The paper is based on C¹²O₂¹⁶ rotational constants and line frequency data gained from laser frequency measurements performed recently. Equations for transition frequencies and their standard deviations have been derived. A list is presented containing accurate 10.4 and 9.4 μm line frequencies and their relative and absolute standard deviations; also wavenumbers and wavelengths are given for each line. For transitions usually observed in CO₂ lasers the relative standard deviations are on the order of a few megahertz, the absolute accuracy is about 25 MHz for the 10.4 μm band and about 18 MHz for the 9.4=μm band.
