Plot the vibrational energy level separations (DG+w) in the P state of BH and determine the dissociation energy (D) by performing a linear extrapolation (Birge-Sponer plot). Fitting of the data to functions that accurately represent the behavior both at the bottom of the potential curve and near dissociation gives D. = 17951 cm', what is the percent error for the linear extrapolation? Try fitting the data to a third order polynomial and determine the dissociation energy. What is the percent error now? (12) 4. Calculate the observed frequencies (in cm*') of the first 3 lines in each branch in the Stokes vibrational Raman spectrum of 12C%0 when a laser at 18274.37 cm' is used to record the spectrum (see Table 11C.1 for the spectral constants).
