Vibrational Relaxation of CO by Fe-Atoms.

Abstract

Shock tube investigations on Fe(CO)5 + Ar mixtures are described. Behind incident shocks we observe immediate decomposition of the iron pentacarbonyl to yield Fe and vibrationally cold CO; the CO is then very efficiently relaxed by the Fe-atoms. The results are interpreted to yield a relaxation time for CO infinitely dilute in Fe at 1 atm of P(tau)(CO, Fe) of about 0.06 atm micro sec for T = 1400-2900K. This is believed to be the first measurement of vibrational relaxation by metal atoms. (Author)
