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.
