 Welcome to this webiste.
 On this website you can watch reference data for excitations the base data are
 
-- Absorptions \\(E_\text{Abs}\\).
-- fluorescence \\(\Delta E_\text{Fluo}\\).
+- 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 :
+Other data are calculated with this quantities with the following equations :
