The three atomic emission spectra for Ytterbium can be shown on graph bellow: NIST Atomic Spectra Database [1], gfall.dat file from Kurucz CD-ROM No. 23 [2] and AtomTrace database. Lines in the AtomTrace list were observed in the optical emission of laser induced plasmas, and the respective values of spectroscopic constants are taken from [1].

You can enable and disable each database by clicking on the legend on the right side. Graph can be controled by the buttons on the control panel on the right top side.

Line spectrum servers only for visualization purposes, the intensity of each line was generated according to following equation: A_{ ki }g_{ k }\cdot e^{ -\frac{ E_{ k } } { Tk_{ B } } }
where T is thermodynamic temperature, artificially chosen as 10^4 K and k_B is Boltzmann constant 8.617330310 \times 10^{ -5 }\mathrm{ eV }\cdot\mathrm{ K }^{ -1 } and A_{ ki } , g_k and E_k are spectroscopic properties taken from [1]. The broadening of lines is artificial, generated with Gaussian and Lorentzian convolution filters.
