Data Analysis

Textual Material

This project provides students with a guided introduction to several topics of importance to the analysis of data; these are the: uncertainty inherent in measurements and how that uncertainty affects results importance of examining data visually before trying to characterize it quantitatively comparison of two data sets to determine if they provide different results modeling of…

Chemical Equilibrium

00. Complete Active Learning Units with Supporting Text, a. Acid-base titrations, a. General equilibrium concepts, b. Acid-base equilibria, c. Complexation equilibria, d. Solubility equilibria, In Class Activities, Textual Material

A series of collaborative learning activities and accompanying text that develop chemical equilibrium, including acid-base chemistry, formation of water-soluble complexes, and solubility are provided. These activities are intended to be done in class by students working in groups, but can be modified for use as out-of-class exercises. Learning objectives, an instructor’s manual, and out-of-class problems are…

Signals and Noise

Textual Material

This e-module provides an introduction to the analytical chemist on the following topics: The significance of signal and noise in chemical measurements The origin of noise in chemical measurements How noise degrades useful chemical information The statistical treatment of noise and the definition of a signal-to-noise ratio Methods used to improve the reliability of chemical measurements…

Lasers

Textual Material

This module discusses basic concepts related to Lasers. Lasers are light sources that produce electromagnetic radiation through the process of stimulated emission. Laser light has properties different from more common light sources, such as incandescent bulbs and fluorescent lamps. Typically, laser radiation spans a small range of wavelengths and is emitted in a beam that is…

Nuclear Magnetic Resonance Spectroscopy

00. Complete Active Learning Units with Supporting Text, g. NMR, In Class Activities, Textual Material

Introduction The goal of this unit is to develop introductory concepts on nuclear magnetic resonance (NMR) spectroscopy that are most relevant for undergraduate chemistry majors. Development of the concepts of NMR is accomplished through an examination of the normal hydrogen (1H) nucleus. The unit is focused on understanding what occurs in molecules and within the NMR…

Basics of NMR

Textual Material

An online text on the basics of Nuclear Magnetic Resonance (NMR) spectroscopy. The text contains information especially appropriate for the novice, but topics are treated at sufficient depth to be useful for more advanced students. This resource features animations that illustrate complex NMR concepts such as precession and the rotating frame of reference. Resource Basic of…

Quantitative NMR

Textual Material

Quantitative nuclear magnetic resonance (Q-NMR) measurements are especially useful for analysis of complex samples where high specificity is needed or when a pure standard of the analyte is not available. Often the sample can be analyzed with a minimum of preparation. Q-NMR has utility in various areas including: Purity analysis Food and wine quality analysis Impurity…

Atomic Emission Spectroscopy (AES)

Textual Material

This module provides an introduction to Atomic Emission Spectroscopy (AES). AES is a broad area that includes several analytical chemistry techniques focused on elemental analysis, the identification, quantification, and (sometimes) speciation of the elemental makeup of a sample. AES can be an extremely useful tool and is utilized in academic and industrial settings within biological and…
