A theoretical description of line mixing in the Q branch of an infrared rotation-vibration band is obtaibed in the weak coupling approximation. The description is applied to the case of the ν2 band of CO2 near 667 cm-1. Theoretical absorption profiles are given for selected spectral regions corresponding to representative values of the pressure. A comparision is made between the weak coupling results and the results of a forthcoming dynamical calculation of the absorption band shape.
Founded in 1916, the Optical Society of America (OSA) was organized to increase and diffuse the knowledge of optics, pure and applied; to promote the common interests of investigators of optical problems, of designers and of users of optical apparatus of all kinds; and to encourage cooperation among them. The purposes of the Society are scientific, technical and educational.
The Optical Society of America brings together optics and photonics scientists, engineers, educators, and business leaders. OSA's membership totals 15,500 individuals from over 95 countries. Approximately 47% of the Society's members reside outside the United States.
