Etude des intensités et des largeurs des raies de vibration–rotation de la bande deuxième harmonique de l'anhydride carbonique à 6970 cm−1 par déconvolution numérique

Abstract

The intensity and half-width of the ¹²CO₂ 3ν₃ band lines are determined, the instrumental effects being corrected by numerical calculations. The square of the vibrational moment (R₀³)² is found to be equal to 0.233 × 10⁻⁴² e.s.u. With a quadrupolar momentum Q = 5.2 × 10⁻²⁶ e.s.u., the line-width variation curve versus J can be approximately interpreted by Anderson's theory.
