McCubbin, Jr., Ronald Darone, and James Sorrell, Determination of Vibration-Rotational Line Strengths and Widths in $CO_{2}$ using a $CO_{2}-N_{2}$ Laser, Applied Physics Letters 8, 118 (1966).Author Institution: Physics Department, The Pennsylvania State University; U. S. Military Academy, West Point, New York.The strengths, self-broadened widths, and foreign gas broadened widths for A, $N_{2}$, and air have been measured for several lines in the 10.4 micron $CO_{2}$ band using the laser $method.^{1}$ The strengths and foreign broadened widths were derived from the transmittance vs. pressure curves assuming a Voigt line-profile. The ratio of line-strength to self-broadened width was determined from the constant transmittance observed for pressures above about $^{1}/_{10}$ atmosphere
