Chemistry 2710 Spring 2000 Practice Problems

  1. The vibrational energy level spacing in carbon monoxide is tex2html_wrap_inline17 . Calculate
    1. the vibrational frequency, and
    2. the ratio of the number of molecules in adjacent energy levels at several different temperatures in the range 10-1000K. Plot the results of these calculations against tex2html_wrap_inline19 .
  2. The amino acid tryptophan absorbs light at 280nm. This absorption is due to an electronic transition. We can calculate from the wavelength that the electronic energy levels involved in this transition are tex2html_wrap_inline21 apart. Calculate the ratio of the numbers of molecules in the two states at room temperature.
