✦ Synopsis

The mechanism for activation of infrared absorption by N, matrices has been studied. FTIR spectra of isotopically enriched CO, trapped in N, provide new and convincing evidence supporting the hypothesis proposed by Nelander that the activation is electromagnetic in origin for the CO,/N, system. The N, absorption appears to be triggered by the near coincidence of the N, stretching frequency with the asymmetric stretch of C1601s0. The activation of absorption by N, in matrices doped with H,O and C,N, has also been observed. For these systems, however, alternate explanations for the activation appear to be necessary.
