Abstract

The OH(A-X) and OD(A-X) emission spectra have been measured by 17 eV electron impact on the mixtures of H₂O and D₂O with several mixing ratios. The intensity ratio of the OH(A-X) emission to that of OD(A-X), q, in the spectra of the mixture has been estimated using the OH(A -X) and OD(A-X) spectra obtained from pure H₂O and pure D₂O. As a result, q is proportional to the ratio of the H-atom quantity to the D atom in the mixture, indicating that q is independent of the fraction of HOD in the mixture. The following emission intensity ratios are obtained. σ _HOD→OH/σ_HOD→OD=H₂O→OH/σ D₂O→OD=0.53±0.02,σ_D _2O→OD/σ_HOD→OD = 1.88±0.24, where σ_HOD→OH means the total emission cross section of OH(A-X) by electron impact on pure HOD, and the others are similar.
