Example for blended lines: a) Spectrum recorded by LOGS at around 12 715 cm^-1 showing the overlap of two Nb lines as well as another spurious line. b) Spectrum recorded by LIFS with fluorescence λ_f = 532.15 nm: transition from 14 899.26 cm^-1, J = 5/2 − → 27   614.10 cm^-1, J = 5/2 at λ_air = 786.266 nm or σ_vac = 12   714.84 cm^-1. c) Spectrum recorded by LIFS with fluorescence λ_f = 581.94 nm: transition from 17 476.22 cm^-1, J = 11/2 − → 30   191.25 cm^-1, J = 13/2 at λ_air = 786.255 nm or σ_vac = 12   715.03 cm^-1.
