Description
Summary:A modification to the classic FTIR diatomic gas experiment performed in the undergraduate physical chemistry laboratory is described. A "real-world" sample source in the form of cigarette smoke has been incorporated and students are asked to identify the principal components present by analyzing the rotationally-resolved infrared spectra to determine fundamental molecular constants for each species observed. The analysis is facilitated by the use of Chem Spec II software. Chem Spec II is a noncommercial software package designed to emulate standard spreadsheet programs such as Excel or Quattro Pro and aid students with the assignment and analysis of rotationally resolved infrared spectra.
