(20 pts) 6. (a) Consider a molecule with two Franck-Condon active vibrations with "Trequencies" Vi = 600 and v2=1500 cm-1, with displacement parameters λι = 1.0 and λ2-2.0 for electronic excitation to a certain excited electronic state. All other vibrations have λ=0.

The following data were obtained for an excited electronic state of Mgo. rotational constant, B = 0.5014 cm vibrational constant, .= 632.5 cm a) At what energy (in cm) and wavelength (in um, where 1 um = 10 m) will the J = 6 to J - 7 rotational transition occur for this electronic state of Mgo? b) What is the value for...
4. Anharmonic potential (15 points) The adjacent figure shows the experimentally determined potential energy curve of the electronic ground state of"Br2, with a few of the vibrational levels. The vibrational transitions are reasonably well described by a harmonic oscillator model, but much more accurately by including a small anharmonic correction term: En/hcVe(n 1/2) - vexe(n + 1/2)2. From fits to experimental data, the values of the constants are 325.32 cm and exe 1.08 cm .5 10 15 (a) Calculate the...
