+# Welcome
 Welcome to this webiste.
 On this website you can watch reference data for excitations the base data are
+## Data present on datafiles
 
 - Absorptions \\(E_\text{abs}\\).
 - fluorescence \\(\Delta E_\text{fluo}\\).
 - ZPE delta \\(\Delta E_\text{ZPE}\\).
 
-Other data are calculated with this quantities with the following equations :
+## Calculated data
 
 <div>$$ E_\text{adia} \simeq \frac{E_{abs}+E_{fluo}}{2}\ $$</div>
 <div>$$ E_\text{0-0} \simeq E_\text{adia}-\Delta E_\text{ZPE} $$</div>
