Infrared chemiluminescence in the reactions of atomic fluorine with ethanol, propanol-(2) and some deuterated analogs

Abstract

In the reactive systems F+C 2H 5OH, F+C 2D 5OD, F+C 2H 5OD, F+(CH 3) 2CHOH, F+(CD 3) 2CHOH, and F+(CD 3) 2CDOH the infrared emission spectra were recorded from HF and/or DF in the fundamental region. Hydrogen abstraction takes place from CH and OH bonds. Vibrational relaxation was suppressed and rotational relaxation took place only to a minor extent. HF(DF) excitation reaches the thermodynamic limit within error limits in all cases. The vibrational distributions of HF for the systems F+(CD 3) 2CHOH, F+(CD 3) 2CDOH show no populati inversion. The vibrational distribution of HF for all other systems and all the DF vibrational distributions obtained show population inversion. Inform theory was used to describe the results of those reaction channels that could be studied separately because of isotopic substitution. The results are c to the systems F + methanol and deuterated analogs investigated before in our laboratory, and to the F+CH 4, F+CD 4, and F+H 2O 2 reactio
