Unformatted text preview: [1] Application of PIB model to conjugated bonds. Lets use more accurate numbers: 132 and 150 pm for C=C and CC bonds instead. [2] Quantum dots. Please use the particle in a 1D box model to explain the reason why: when the size of a quantum dot gets larger, the color of the emitted photon due to the n=2 n=1 transition shifts to red. (Remark: PIB is good enough for now; a better model for quantum dots should be particle in a spherical box)...
