Abstract
The effect of CHCl3 vapor on rare-earth metal vapors in an acetylene-air flame has been studied spectroscopically. It has been established that both the molecular spectra of the oxide molecules and the emission spectra of the atoms (Eu, Yb) are weakened in the presence of this vapor. In the case of europium and lutecium, the spectra contain new (chloride molecule) bands. Investigation of the relationship between the emission intensities of the atoms or molecules and the partial pressure of chlorine in the flame suggests that molecules of the MeCl2 type are formed in the flame.
