Abstract:High-resolution spectra recorded with Fourier transform spectrometers (FTS) have been analyzed to determine line positions and intensities for transitions in the 1$\leftarrow$0 bands of $^{12}$C$^{16}$O, $^{13}$C$^{16}$O, $^{12}$C$^{18}$O and $^{13}$C$^{16}$O, and air-broadened half-width and shift coefficients, their temperature dependences, line mixing and speed dependence parameters were measured for $^{13}$C$^{16}$O and $^{12}$C$^{18}$O transitions. These parameters were retrieved from two multispectrum fittings (1940-2260 cm$^{-1}$) of a data set that included two room-temperature spectra of a natural sample of CO recorded with the Kitt Peak FTS and self- and air-broadened spectra (up to 626 Torr) of $^{13}$C-enriched and $^{18}$O-enriched CO samples between 150 K and room temperature recorded with the JPL Bruker IFS-125HR FTS. Sample cells with path lengths of about 0.5, 1.1, 4.3 and 20.4 cm were used, and all but the shortest cell were temperature controlled. The retrieved 1$\leftarrow$0 band strengths of $^{12}$C$^{16}$O, $^{12}$C$^{18}$O and $^{13}$C$^{18}$O are very close to the HITRAN2012\footnote{L.~S.~Rothman et al.,\textit{JQSRT} \underline{\textbf{130}} (2013) 4-50.} values, but for $^{13}$C$^{16}$O the band strength is $\sim$4.5$\%$ larger than the HITRAN2012 value and 2.6$\%$ higher than the HITRAN2016\footnote{I.~E.~Gordon et al.,\textit{JQSRT} \underline{\textbf{203}} (2016) 3-69.} value.\footnote{Research described in this talk was performed at Connecticut College, the College of William and Mary, Langley Research Center and the Jet Propulsion Laboratory, California Institute of Technology, under contracts and cooperative agreements with NASA.}
