Laboratory Experiments
The Chemical Bond Studied by IR Spectroscopy in Introductory Chemistry: An Exercise in Cooperative Learning
Janet S. Anderson, David M. Hayes, and T. C. Werner

Abstract
The concepts of bond strength, resonance, and hydrogen bonding are discovered in freshman chemistry laboratory by taking infrared spectra of organic molecules. In order to allow one or two instruments to serve a laboratory section of 24 students, the experiment is divided up among small groups of students, and methods of cooperative learning are used to allow students doing different sections of the experiment to share their results with the rest of the class. The laboratory is designed so that students can discover certain principles on their own. Using instrumental techniques early in chemistry courses stimulates student excitement and shows students what kind of information is available to chemists at the molecular level.
