# 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}\\).

## 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>
