Abstract
The oxides of alkaline earth metals have extremely low vapour pressures and a strong tendency to aggregate in the gas phase. We have observed the infrared spectra of the monomeric species CaO and BaO in a low pressure flame by reacting hot metal vapours with nitrous oxide.
By comparing the relative intensities of adjacent transitions, the distribution over the rotational and vibrational states of CaO has been examined. The vibrational temperature and the concentration of CaO monomers varied strongly with flame conditions.
