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...

question 10.1? 10.2?
The energy of an electron in a Hydrogen atom for a particular level is given by where n is a positive integer (eg. 1,2,3..), denoting the energy level, me is the mass of the electron, e is the electron charge, eo is a physics constant, and h h/2m, where h is Planck's constant [10.1] Question: Simplify equation 10.1 to put it into the form En-C/n2 where C is a constant [10.2] Question: Determine the value of En...

Consider an electron in a one-dimensional box as a model of a quantum dot. Suppose the box has width 0.7 nm. For this problem, absorption of light and subsequent relaxation connect two states (i andj) with a difference in energy, AEi E - E. (a) Calculate AEsi and AE2I for luminescence from excited energy levels to the ground state. Convert the energies to the corresponding wavelengths of light, λ31 and λ21. (b) Find the wavelength of light that corresponds to...

The quantum-mechanical treatment of the H atom gives the energy, E, of the electron as a function of n: where h is Planck's constant, me is the electron mass, and a0, called the Bohr radius, is 52.92×10−12 m. Calculate the wavelength in nm of the photon emitted in the jump between n = 1 and n = 4.

3. The quantum harmonic oscillator is the quantum-mechanical analog of the classical harmonic oscillator. Because an arbitrary potential can usually be approximated as a harmonic potential at the vicinity of a stable equilibrium point, it is one of the most important model systems in quantum mechanics. Consider an electron trapped by a one-dimensional harmonic potential V(x)=-5 mo?x” (where m is the electron mass, o is a constant angular frequency). In this case, the Schrödinger equation takes the following form, **...
