Abstract: The spectra of some volatile hydride forming elements have been investigated to select thermometric species for determination of excitation temperature in analytical plasmas working in argon under atmospheric pressure. Groups of lines of As I, Sb I and Sn I in addition to Ar I were found appropriate for the determination of excitation temperature in inductively coupled plasma (ICP) and wall-stabilized arc (WSA). The Boltzmann plots were straight lines, which determined temperature in ICP and WSA using different groups of spectral lines that agree well with each other as well with the most familiarly used thermometric species. These lines are recommended for determination of temperature when gaseous hydrides are introduced into the plasma and no other thermometric species except the atoms of working gas are present.
