Molecular and Atomic Spectroscopy

00. Complete Active Learning Units with Supporting Text, a. Basic spectroscopic concepts, b. Beer's Law, c. UV/Vis, d. Infrared, e. Fluorescence/Luminescence, f. Raman, h. Atomic Spectroscopy, In Class Activities, Textual Material

A series of collaborative learning activities and accompanying text that develop the areas of molecular and atomic spectroscopy is provided. Chapters on basics of spectrophotometry, ultraviolet/visible absorption, molecular fluorescence, infrared, Raman and atomic spectroscopy are included. These activities are intended to be done in class by students working in groups, but can be modified for use…

UV/VIS Spectroscopy

c. UV/Vis

Students explore basic aspects of UV/Vis spectroscopy including effects of conjugation, non-bonding electrons and solvent on the observed spectrum. There is an associated text that explains the answers to the questions on the worksheet.

UV/VIS Spectroscopy

c. UV/Vis

In this activity, students prepare a solution, record spectral data, and then complete several statistical analyses of the data.

Spectral Dataset with Suggested Uses

c. UV/Vis

A spectral dataset is provided and suggestions for activities to students explore are described.

End Creek: Spotted Frogs and Aquatic Snails in Wetlands – A Water Quality Investigation

22. Contextual Modules, a. Designing a sampling plan, b. Sample preparations, c. UV/Vis, Contextual Modules, d. Potentiometric Methods, h. Atomic Spectroscopy

Introduction This module provides a context for introducing fundamental techniques used in chemical analysis (spectrophotometry, atomic absorbance spectroscopy and ion selective electrodes) along with considerations about sampling and sample preservation. Using an active learning approach, the module explores some fundamental water quality parameters such as the concentration of inorganic cations and anions that…

Optical Properties of Gold Nanoparticles

22. Contextual Modules, c. Microscopy, c. UV/Vis, Contextual Modules

Introduction The module is designed as a sequence of class activities and provides a set of experimental data (TEM images, size and size distribution analyses, and absorbance vs. concentration data) that can be downloaded from the ASDL site. Alternatively, if the instructor has access to a transmission electron microscope and a UV-VIS spectrophotometer, the module could…
