Students in CHEM310L will complete all of this module, including both Part I (\(\ce{HCl/DCl}\)) and part II (\(\ce{SO2}\)).
Reading assignment
This experiment involves many calculations; advanced knowledge of what you will have to do will be very helpful. In preparation for this experiment please read Experiment 37 in Shoemaker, Garland and Nibler beginning on page 397. You will want to read and understand the theory section including the subsections involving selection rules and isotope effects. In addition to this information read this module (not that there are two parts, and what you do depends on your course number). Additional references below are strongly recommended.

Written assignment
In addition to the usual prelab work expected for all experiments in the course (Introduction and Experimental Plan), please complete the following and submit the work prior to the lab meeting.
For Part 1 (CHEM310L and 301L), show which equations you would use to find: \(B_e\); \( \alpha_e\); \(\tilde{\nu_o}\); k; \(\large \frac{\tilde{\nu_o}^*}{\tilde{\nu_o}}\); and \(\large \frac{B_{e}^{*}}{B_e}\)
For Part 2 (CHEM310L only), show which equations you would use to determine: \(k_1\); \(\large \frac{k_{\delta}}{\ell^2}\); \(\tilde{C_{v}} (vib)\)
Helpful videos
These videos provide a nice introduction and demonstration of the theory and techniques you will use.
