Near-Resonant Vibrational Energy Transfer inN2-CO2Mixtures

Abstract

Recent experiments indicate that the ${\mathrm{N}}_2$-C${\mathrm{O}}_2$ near-resonant vibration-transfer cross section has a strong negative temperature dependence for temperatures below about 1000°K, in contrast to the behavior predicted by the theory of Schwartz, Slawsky, and Herzfeld. It is shown that this anomalous behavior is due to the long-range dipole-quadrupole interaction between the molecu
