Abstract

Molecular absorption spectrometry by electrothermal volatilization in a graphite furnace. Part 1. Basis of the method and studies of the molecular absorption of gallium and indium halides A new principle of analysis — molecular absorption spectrometry (m.a.s.) by electrothermal volatilization of simple molecules in a graphite furnace — is proposed. The absorption spectra of GaX and InX molecules were measured (X = halogen). Strong absorption bands were found for GaO, GaF, GaCl, InO, InF, InCl and InBr. The GaBr molecule showed only a weak continuum. Absorption bands were not found for the GaI and InI species, which do not exist in the plasma of the graphite tube. The results are compared with literature data. The use of m.a.s. for determinations of traces of halogens is outlined.
