Chlorine monoxide (ClO) is thought to play an important role in a photochemical cycle which causes the destruction of ozone in the earth’s stratosphere. Since lines of the (1,0) fundamental of ClO lie near 14C16O2 laser lines, IR heterodyne spectroscopy is potentially an important technique for monitoring the ClO abundance. However, due to the presence of lines from other trace atmospheric gases in this spectral range, the interpretation of such observations is ambiguous unless high-resolution laboratory measurements support the identifications. We report here measured frequencies for spectral lines of seven trace atmospheric gases which absorb near the 14C16O2 laser transitions relevant to the detection of ClO by IR heterodyne spectroscopy.

All lines not given a specific vibrational designation are in the ν1 band (1000–0000) of 16O12C32S.
Uncertainties in these numbers are given in parentheses in units of the last digit. The uncertainties are estimated to be ±1 σ in the absolute accuracy of the numbers.
These numbers are from Refs. 12 and 14. The uncertainty in these numbers (except where noted) is ±0.00004 cm−1 corresponding to an uncertainty in frequency of ±1.2 MHz.
Positions of these lines were estimated visually.
Uncertainty in these numbers is ±0.00015 cm−1 corresponding to an uncertainty in frequency of ±4.5 MHz.
Line is blended due to overlap with another line in the opposite sideband.
All identified lines are in the ν2 (010–000) band of NO2.
Uncertainties in these numbers are given in parentheses in units of the last digit.
These numbers are from Ref. 16. The uncertainty in these numbers is ±0.002 cm−1 corresponding to an uncertainty in frequency of ±60 MHz.
Sidebands of these lines were identified by detuning the laser as described in the text.
Identification of this line is particularly uncertain; if the line is in the opposite sideband to that assumed, the position would be 858.1975 cm−1.
All identified lines are in the ν5 band.
Uncertainty in these numbers (except where noted) is ±0.0004 cm−1 corresponding to an uncertainty in frequency of ±12 MHz.
Line is blended due to overlapping sidebands. The uncertainty in the number is ±0.0008 cm−1 corresponding to an uncertainty in frequency of ±25 MHz. See text for details.
Line is blended due to overlapping sidebands. The uncertainty in the number is ±0.0008 cm−1 corresponding to an uncertainty in frequency of ±25 MHz. See text for details.
All identified lines are in the ν9 band of C2H6.
Uncertainties in these numbers are given in parentheses in units of the last digit.
These numbers are from Ref. 18. The uncertainty in these numbers is ±0.0005 cm−1 corresponding to an uncertainty in frequency of ±15 MHz.
Both upper and lower sideband wave numbers are given for the unidentified lines since the sidebands for these lines are not determined. However, see text.
