Introduction: The First Law of Thermodynamics places important restraints on the path that can be taken by a system but it does not define the path. For example, the First Law does not rule out the possibility of warming oneself by sitting on a...

Experiment designed to introduce the fundamental principles and practice of magnetic resonance imaging (MRI), a form of NMR spectroscopy, by obtaining and examining a two-dimensional image of the stem or bud from a plant.
Chemistry-Study and teaching; Absorption spectra; Molecular spectroscopy; Thermodynamics; Statistical mechanics
Experiment involving an introduction to molecular spectroscopy and the extraction of molecular parameters and thermodynamic properties from an analysis of the vibrational fine structure of an electronic band spectrum of gaseous iodine.
Chemistry-Study and teaching; Voltammetry; Electrochemistry; Solution (Chemistry)
Experiment with the goal of gaining an understanding of anodic stripping voltammetry and an understanding of the factors involved in performing quantitative analytical determinations, through the determinations of amounts of copper.
Chemistry-Study and teaching; Handouts; Quantum theory; Eigenfunctions; Perturbation (Quantum dynamics)
Handout on perturbation theory in quantum mechanics written by the instructor as a supplement to the textbook. It looks at an approach for the case where a problem differs slightly from one that can be solved exactly.
Handout explaining systematic and random errors, precision versus accuracy, significant figures, absolute and relative error, propagation of errors, measurement distribution, etc.

Introduction. In class we observed that no reaction goes to completion and have discussed qualitatively the consequences of this insight. It is also possible to deal quantitatively with chemical equilibria. The chemist's approach should start with...
Handout from the laboratory manual explaining curve fitting and the method of least squares. Included is a least squares exercise using Microsoft Excel.

Experiment previously used in the course, meant to introduce the student to molecular spectroscopy and to the molecular parameters and thermodynamic properties which can be obtained by analyzing the vibration-rotation spectrum of gaseous hydrogen...
Chemistry-Study and teaching; Handouts; Stoichiometry; Chemical equilibrium
Introduction. Part II of the handout will apply the approach introduced in Part I to acid-base chemistry. We shall focus on two cases where the application of stoichiometry leads to great simplifications: strong acids which are essentially 100%...
