Query: On the opportunity of spectroscopic determination of absolute atomic
  densities in non-equilibrium plasmas from measured relative intensities
  within resonance multiplets distorted by self-absorption   The opportunities of the application of the recently proposed approach in
optical emission spectroscopy of non-equilibrium plasmas have been studied. The
approach consists of several methods of the determination of {\em absolute}
particle densities of atoms from measured {\em relative} intensities within
resonance multiplets distorted by self-absorption. All available spectroscopic
data concerning resonance spectral lines of atoms having multiplet ground
states from boron up to gallium were analyzed. It is found that in the case of
C, O, F, S and Cl atoms an application of the methods needs VUV technique,
while densities of B, Al, Si, Sc, Ti, V, Co, Ni, Ga atoms may be obtained by
means of the intensity measurements in UV and visible parts of emission spectra
suitable for ordinary spectrometers used for optical diagnostics and monitoring
of non-equilibrium plasmas including industrial plasma technologies.
