Temple University - Department of Chemistry CHE 3302 - Spring 2013 Problem Set#9 Due 4/30/2013 1) Consider a molecule with a spacing between two energy levels of 0.250 kJ mol -1 . Calculate the wavelength and wavenumber of the photon that would be needed to lead to an excitation between two successive levels. What part of electromagnetic spectrum will this transition occur in? 2) Consider a hypothetical circumstance where the selection rule for a pure rotational transition was J= ± 2. Derive an analogous expression for eqn. 12.21a (Atkins) for this circumstance. 3) Read Further Information 12.2 (pg. 483) in Atkins. Now consider an electric dipole transition from ν =0 to ν =2. Show that it is forbidden by writing out the wavefunctions and showing < ν f |x| ν i >=0. Do this by noting that the integrand to be evaluated is a product of an even function times an odd function so integrating from -x to x yields zero. 4) Consider the H 79 Br molecules. Its equilibrium bond length is 141 pm. Calculate the rotational constant, B. Also consider a J=2 to J=3 transition.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
