Atomic line plots and minimal and maximal spectra for every element
In this section we show atomic line plots for base state and first ion for almost every element up to element number 92 uranium. These are the basis to how to read unknown elemental emission spectra and to build simulated spectra for our elemental analysis by parameter estimation. The principle of these plots is explained in section x.x.x on atomic line plots and code to produce these is in notebook xx. Lines of low upper energy positioned low in the plot and high probability of transition drawn large are those you are most likely to see to in a LIBS spectrum. These are built based on atomic line lists by Kurucz.
Under the atomic line plots we draw(TODO! NOT YET ADDED) two example simulated spectra from each element, so called minimal and maximal spectra. The selected values of temperatures and electron densities to produce the minimal and maximal spectra are selected somewhat arbitrary based on my own comparisons to experimental LIBS spectra so they might not be such a good fit for other LIBS equipment. They are not the objective truth minimal and maximal but a practical tool where minimal spectrum is used to identify element and maximal spectrum is used to identify peaks.

1 H Hydrogen
2 He Helium
3 Li Lithium
4 Be Beryllium
5 B Boron
6 C Carbon
Note that molecular peaks are not included in this and for Carbon LIBS spectrum the molecular peaks are important and can be dominant. Carbon molecular peaks are explained in chapter xxx.
7 N Nitrogen
8 O Oxygen
9 F Fluorine
10 Ne Neon
11 Na Sodium
12 Mg Magnesium
13 Al Aluminium
14 Si Silicon
15 P Phosphorus
16 S Sulphur
17 Cl Chlorine
Chlorine lowest excitation energies are quite high at over 80000 eV so they requiring high temperatures to be visible and thus chlorine signal usually quite weak in LIBS.
