Problem P13B.3

This problem is best done using mathematical software. Equation 13B.15 is the partition function for a harmonic oscillator. Consider a Morse oscillator (Topic 11C) in which the energy levels are given by

$$E_{v}=\left(v+\frac{1}{2}\right) h c \tilde{v}-\left(v+\frac{1}{2}\right)^{2} h c x_{e} \tilde{v}$$

Evaluate the partition function for this oscillator, remembering to measure energies from the lowest level and to note that there is only a finite number of bound-state levels. Plot the partition function against $$k T / h c \tilde{v}$$ for values of $$x_{\mathrm{e}}$$ ranging from 0 to 0.1, and-on the same graph-compare your results with that for a harmonic oscillator.

Chem 142: Week 7: Lectures 4.1-4.4 Chapters (4.1-.6, 4.8, 4.9-.12) Key and Introduction: If you see text in this purple color, it just means that I have added side notes that I thought were significant from the textbook reading. (exclude the purple that I have used on page 5) Words in bold are important vocab words included for this week My note summaries are all based off of lectures and textbook readings. I will upload notes once every week summarizing notes, lectures, and textbook readings from class. Each week will have a different theme to make these notes a bit more colorful. I hope you enjoy these notes!!! If there are anything that you think would help my notes to become more beneficial, please leave comments below my post. Thank you.
