Accurate calculations of the transfer of radiation in the 15-micron band of carbon dioxide require a knowledge of the real structure of the bank as well as the replacement of the usual relaxation equation by the system of gas-kinetic equations. The probabilities of nonelastic collisions, taking into account Fermi resonance, are computed. The vibrational relaxation time of carbon dioxide in dry air at 200 deg K and 1 atm pressure is expected to fall within the interval 2 to 20 x 0.0000001 sec. The contribution of water vapor to the relaxation time of carbon dioxide is discussed. (See also P-3595, P-3596.) 23 pp. Bibliog.

This report is part of the RAND Corporation Paper series. The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
