Figure 8.1: Axial and radial distribution of the excited species produced in the helium
plasma during the destruction of CCl4. Figures from a to g and i correspond to
excited species from destruction of CCl4 and subsequent recombinations. In the
figures d and e appear copper as an element introduced into the plasma by erosion
of the tip of the torch. Figures h, j and k show excitement of the elements of the
surrounding air outside the plasma. The gradation of colors corresponds to the
intensity of the lines in arbitrary units. The wavelengths and the molecular
transitions of the lines and the rotational bands used in of each figure are: a) Cl I
(754.7 nm), b) Cl II (479.4 nm), c) Cl III (374.9 nm), d) Cu I (296.1 nm), e) CuCl
