Calculate the energy levels of the π network in hexatriene. C6H8, using the particle in the 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. What is the wavelength of light required to induce a transition from the ground state to the first excited state? How does this compare with the experimentally observed value of 240nm? What does the comparison made suggest to...

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...

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...
