  (Vib) DCB 467.94 cm^-1 (twist)

The major peaks shown on the plot are described with the following vibrations. Smaller peaks within the finger print region are due to the individual vibration of each atom within the
molecule- the number of vibrational degrees of freedom is equal to (3n-6= 3*12-6) 30.

 UV-Vis data for the promotion of an electron from the ground state,

Level of theory Excited State Evergy (eV) Oscillator Strength Literature value
6-21G 5 8.47 1.551648 4.681799336

6 8.67 0.957871 5.519
6-31G 5 8.35 1.599756

DZV 5 8.26 1.617477

6 8.38 1.051128
Literature Values: Hellmann, M; Bilbo, A. J.

The calculated energies for the promotion of an electron from the ground state differ from the literature value because calculations do not transverse well to the actual experiments.  As with many equations, they do not account for everything happening inside the molecule and will not have the exact energes seen in experiments.
