Different methods have been applied in order to determine the ionic assignment of spectral lines. Several techniques have been developed: from classical methods, where excitation energy is increased to observe the emitted radiation from consecutive ions [1] - [7] , to the more recent ones, like the determination of energy level lifetimes (8) or plasma electronic density measurements (9) . All of these methods must be considered as complementary and, due to that reason, the results cannot be derived a priori in opposition to experimental data or interpretation....

Recently Petit et al.published a paper devoted to a high-resolution spectroscopy study of the 0-0 laser band in the Second Positive System of molecular nitrogen and explaining the optical gain formation on its different branches.All the results by Petit et al. are equivalent to those previously published by Massone et al.and are in accordance with theoretical predictions reported by Tocho et al.Summarizing, we would comment as follows....
