Abstract
“The energy distribution in the infrared spectrum of carbon dioxide has been studied as a function of temperature, up to $1273^\circ K$. Values of spectral absorption and integrated absorption were calculated from spectra of heated $CO_{2}-N_{2}$ $mixtures^{1}$ Composition and pressure of the samples were constant; hence the temperature effect could be isolated. The effect of temperature on the observed spectrum is related to the change with temperature of the vibrational energy distribution. In order to study this effect, the vibrational distribution of the molecular population was calculated for temperatures up to $1273^\circ K$. All appreciably populated vibrational levels were included in the calculations. Comparison of the calculated distributions to the spectral data will be described.”
