Peer Mentoring in the General Chemistry and Organic Chemistry Laboratories  Caleb A. Arrington, Jameica B. Hill, Ramin Radfar, David M. Whisnant, and Charles G. Bass
This article describes a discovery experiment in which organic chemistry students act as mentors to general chemistry students. Members from both groups work together to isolate an unknown compound using distillation. The structure of the product is then determined collaboratively using IR and NMR spectroscopy.

Analog Spectrophotometers in the Digital Age: Data Acquisition on a Budget  Alexander Y. Nazarenko and Natalie A. Nazarenko
In this article we describe how to employ an inexpensive analog-to-digital converter and a user interface to Microsoft Excel to make a useful computerized spectrophotometer. Readily available types of data loggers, Vernier LabPro and digital multimeters with an RS-232 interface, were utilized. The proposed design does not compromise the quality of the measurements. The conversion of the data to the Microsoft Excel format makes it a convenient tool for a wide range of data processing applications.

The Preparation of a UV-Light-Absorbing Polymer: A Project-Oriented Laboratory Experiment for the Introductory Organic Chemistry Curriculum  Thomas Poon, Jean P. McIntyre, Andrea Dorigo, Drew J. Davis, Matthew A. Davis, Crystal F. Eller, Leah R. Eller, Heather K. Izumi, Kenya M. Jones, Kurt H. Kelley, William Massello, Megan L. Melamed, Cynthia M. Norris, Jeffrey A. Oelrich, Thomas A. Pluim, Sarah E. Poplawski, Jason M. St. Clair, Matthew P. Stokes, Wells C. Wheeler, and Erin E. Wilkes
A laboratory experiment is described that combines organic synthesis, spectroscopy, and polymer chemistry and is suitable for the sophomore organic chemistry curriculum. In this three-week sequence, students synthesize and characterize the UV-absorber 2-(2',4'-dimethylbenzoyl)benzoic acid and incorporate it into films of polymethylmethacrylate.

Using Excel Solver: An Addendum to the HCl Infrared Spectrum Experiment  Mark Iannone
Solver, a flexible and convenient add-in provided with Excel, is useful for fitting of a nonlinear model to experimental data. Solver is introduced to physical chemistry students in the context of the analysis of the fundamental band of the infrared spectrum of gaseous HCl. All peak positions in the P and R branches are used to find least-squares values for the pure vibrational transition, the rotational constants in v = 0 and v = 1 states, and the centrifugal distortion constant.

Determination of DeltaH for Reactions of the Born-Haber Cycle  Richard S. Treptow
Review of the many experimental methods used to determine ?H for the various steps of the cycle for the formation of sodium chloride. Two topics given special attention are the choice of standard state of the electron and the importance of distinguishing lattice enthalpy from lattice energy.
