Chapter 15, Problem 15.44E

Interpretation Introduction

Interpretation:

The expected wavelength of the absorption for $n=3$ to the $n=4$ level in $\text{1, 6-diphenyl-1, 3, 5-hexatriene}$ is to be calculated. The corresponding value is to be compared with the experimental absorption at $350.9\text{nm}$.

Concept introduction:

Electronic spectra are formed by the excitation and relaxation process of electrons. The excitation process is due to the transition of an electron from a lower energy level to a higher energy level. The relaxation process is due to the transition of an electron from a higher energy level to lower energy level.
