Welcome to this webiste. On this website you can watch reference data for excitations the base data are

• Absorptions \(E_\).
• fluorescence \(E_\).
• ZPE delta \(E_\).

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

E_\text{Adia} \simeq \frac{E_{Abs}+E_{Fluo}}{2}\

E_\text{0-0} \simeq E_\text{Adia}-E_\text{ZPE}
