2.5.2. Ionization Potential (IP)

Ionization potential (IP) values were recorded using the following equation [20].

$$\mathbf{I\_P \ (eV)} = 5.76 + 1.53 \times 10^{-4} \text{ v\_{CT}} \tag{4}$$

2.5.3. Energy of the CT Complexes (ECT)

The energies of the CT complexes (ECT) (eV) were calculated using Equation (5).

$$\mathbf{E\_{CT}} = \mathbf{h} \mathbf{v\_{CT}} = 1243.667/\lambda\_{\rm CT} \tag{5}$$
