Abstract
This article describes a laboratory activity appropriate for the college freshman studying general chemistry and general physics concurrently. The activity described is intended to unify for the student the topics of IR spectroscopy and Hooke's Law. This is accomplished by first working with springs and masses and then by acquiring and comparing the IR spectra of chloroform and chloroform-d. Using the IR bands assigned to C-H and C-D stretching, students are requried to calculate periods of oscillation and bond force constants. The activity is intended to help students make the connection between physics and chemistry.

Preparation and Characterization of Bayerite Samples: Use of Diffuse Reflectance Infrared Spectroscopy to Monitor Purification
Nsoki Phambu , Bernard Humbert and Andre BurneauJournal of Chemical Education2002 79 (9), 1117Preparation and Characterization of Bayerite Samples: Use of Diffuse Reflectance Infrared Spectroscopy to Monitor Purification
Nsoki Phambu , Bernard Humbert and Andre BurneauJournal of Chemical Education2002 79 (9), 1117We show here how bayerite, a polymorphic form of aluminum trihydroxides, can be synthesized and characterized by simple spectroscopic methods. Purification of the product by washing with water can be monitored by diffuse reflectance infrared spectra. A ...
