In the ro-vibrational model for spectra of diatomic molecules, the total rotational and vibrational energy for a given state is: Évj = ū(v + 3) + BJC +1) (Equation 1) where v is the vibrational quantum number and J is the rotational quantum number. Complete the following steps to create a model energy level diagram for a hypothetical diatomic molecule with ✓ = 2000 cm-1 and B = 1 cm-1. i) Draw a horizontal line to represent the ground vibrational...
Shown below is the vibration-rotation spectrum of Hydrogen Bromide (HBr), this shows transitions between the v = 0 and v = 1 vibrational levels of the molecule. From the data, estimate the force constant (spring constant) for this molecule, given that the relative atomic weights for H and Br are 1 mu and 80 mu respectively. Why is this vibrational transition split into 2 series of lines with a “missing” line in between them at the center? For each of...

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...

There is a 1-d infinite square well of width a, between x = 0 and a. We also know that V(x) = 0 for 0<x<a and +∞ elsewhere. Then we add a perturbation to it so that V(x) = ?_0 for 0 < x < a/2, and the same as before elsewhere. That is, a flat bump of width a/2 and height ?_0 in the left half of the well. Please answer following 3 questions. 1) Sketch the potential and...
