(1) in class, we said that the electronic states of the π electrons of a conjugated linear-like molecule could be approximated by the wave functions of a particle in a one-dimensional box of length L A) Write down the wave function for a single electron for such a system. Include any restrictions on the quantum number(s). B) Show that the transition probability with x-polarized light for the transition n = 1 → n = 2 is non-zero. C) Show that the transition probability with x-polarized light for the transition n = 1 → n = 3 is zero.
