Part I. The general approach to this experiment is adapted from Shoemaker, D.P., Garland, C.W. and Nibler, J.W., Experiments in Physical Chemistry , 6th edition, McGraw Hill Co. Inc, NY, 1996. 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 the following section on transition intensities is offered. Part II. The general approach to this experiment is adapted from D. P. Shoemaker, C. W. Garland, and J. W. Nibler, Experiments in Physical Chemistry , 6th edition, McGraw Hill Co. Inc, NY, 1996. In preparation for this experiment please read Experiment 35 in Shoemaker, Garland and Nibler beginning on page 383. You will want to read and understand the theory section including the subsections on the valence-force model and the vibrational partition function. 5.4: Data Analysis 9.10.1: Prelaboratory Exercise 9.10.2: Transition Intensities 9.10.3: Part I - FTIR spectrum of a mixture of HCl and DCl gas 9.10.4: Part II - FTIR spectrum of SO2 Thumbnail: Ball and stick model of the sulfur dioxide molecule, \(\ce{SO2}\).
