The experimental technique consisted of measuring the absorption (behind an incident shock wave) of radiation from a single frequency carbon monoxide gas laser; the equilibrium gas temperatures of the plasma ranged from $3000 - 5000^{\circ} K$ . It was found for the temperature range involved that $\sigma = 3.79 \AA$ (independent of rotational quantum number) is a good representation for the optical collision diameter. Experimental determinations of the transition moment (debye) are compared to numerical calculations of the same quantity; the numerical calculations were based on the accurate vibrational potential function reported by A. W. Mantz et $al.^{1}$ and the dipole moment function for carbon monoxide reported by R. A. Toth, et $al.^{2}$ With the exception of a small systematic difference $(\sim 2\%)$ there is excellent agreement between the measured and calculated line strengths. en_US dc.format.extent 243989 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title MOLECULAR LINE STRENGTH MEASUREMENTS VIA LASER ABSORPTION: THE $v'' = 4,\cdots$, 11 $\Delta v=1$ TRANSITIONS OF SHOCK HEATED CARBON MONOXIDE en_US dc.type article en_US
