Abstract

The infra-red emission spectra of the oxy-hydrogen and oxy-deuterium flames and of hot water vapor have been studied in the LiF, NaCl, and KBr regions. The principal features of the spectrum may be accounted for by emission of H2O molecules; no unequivocal evidence for radiation from OH radicals was found with the resolving power available.
