Abstract
Collision-induced absorption is reported in Cl2 and Cl2–Ar gaseous mixtures at room temperature, in the spectral region below 120 cm−1. The results are analyzed according to existing theory, which incorporates estimates of the quadrupole and hexadecapole moments as well as relying on the accuracy of reported Lennard–Jones parameters. In addition, the spectral line shapes are compared with those calculated from information theory for which the theoretical expressions are given for multipole moments. The results for the mixtures are consistent with the generally accepted value of the quadrupole moment, 3.23(±.16) × 10−26 esu (3.23(+.16) Buckingham), and with a theoretical value of the hexadecapole moment, 31.4 × 10−42 esu. If these values of the moments are assumed, the Lennard–Jones parameters of Cl2, are estimated to be σ = 4.20 Å and ε/k = 307 K.
