Use the quantized energy expression of a “particle in a box” for the following problem. Imagine a “linear” conjugated molecule that has a length of 576 pm. To the nearest ones, what is the wavelength of EM radiation (in nm) that will excite a pi electron from n = 4 to the next higher quantum level (i.e., n = 4 +1)? Some helpful information: En = h2n2/(8mea2), where En is the energy of the particle (electron) at the nth quantum...

For a particle in a 1D box with a box length of 1.0 nm, a) Calculate the energy separation between states n-1 and n -2 in eV. b) Calculate the energy separation between states n 8 and n 9 in eV. c) Describe how the energy separation between adjacent energy levels (n and n+1) 4. changes as n increases.
What is the probability of finding a particle between x = 0 and x = 0.25 nm in a box of length 1.0 nm in (a) its lowest energy state (n = 1) and (b) when n = 100. Relate your answer to the correspondence principle. This is an illustration of the correspondence principle, which states that classical mechanics emerges from quantum mechanics as high quantum numbers are reached. What does this all mean? • Only certain (discrete) energies are...
The particle-on-a-ring is a useful model for the motion of electrons around a conjugated macrocycle such as octatetrene, for example. Treat the molecule as a circular ring of radius 0.480 nm, with 10 electrons in the conjugated system moving along the perimeter of the ring. Assume based on the Pauli Exclusion Principle that in the ground state of the molecule each state is occupied by two electrons with opposite spins. (a) Calculate the energy of an electron in the highest...
