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}\\).
- ZPE delta \\(\Delta E_\text{ZPE}\\).

Other data are calculated with this quantities With the following equations :

<div>$$ E_\text{Adia} \simeq \frac{E_{Abs}+E_{Fluo}}{2}\ $$</div>
<div>$$ E_\text{0-0} \simeq E_\text{Adia}-E_\text{ZPE} $$</div>
