Calculate the pi-network in 1,8-diphenyl-1,3,5,7-octatetraene, C20H18, using the particle in a box model. To calculate the box length, assume that the molecule is linear and use the values 135 and 154 pm for C=C and C-C bonds. The electrons in sigma bonds are localized, while eight electrons in pi bonds are delocalized in a box between the phenyl groups (i.e., phenyl groups are not included in the pi-network).
A) What is the wavelength of light required to induce a transition from the ground state to the first excited state?
B) The observed absorption peak is at 390 nm. Does this suggest if the actual box length of the delocalized pi electrons is shorter or longer than the calculated box length by assuming the molecule is linear? Concisely explain your answer

Regarding hexatriene described in the previous question, calculate the wavelength of light required to induce a transition from the ground state to the first excited state using the particle in a box model. To calculate the box length, assume that the molecule is linear and use the values 135 and 154 pm for C=C and C–C bonds, ignore the two ends (3 double bonds, 2 single bonds) Please enter the wavelength in the unit of nm (without entering the unit), with...

7. π electron is an electron which resides in the pi bond(s) of a double bond or a triple bond, or in a conjugated p orbital. The 1,3,5-hexatriene molecule is a conjugated molecule with 6 t electrons. Consider the Tt electrons free to move back and forth along the molecule through the delocalized pi system. Using the particle in a box approximation, treat the carbon chain as a linear one-dimensional "box". Allow each energy level in the box to hold...
