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…
Introduction
This on-line learning module introduces students to Beer’s law with particular attention to the relationships between absorbance, transmittance, and power, and to the fundamental, instrumental, and chemical limitations inherent in the application of Beer’s law. The learning module consists of seven investigations:
Investigation 1: Recalling Beer’s Law Investigation 2: Absorbance Spectra Investigation 3: Calibration Curves…
Students will learn to:
Describe the relationship between absorbance and transmittance.
Develop a proportional relationship between absorbance and concentration.
Account for the role of sample pathlength in absorbance measurements.
Determine the molar absorptivity of a compound based on its absorbance…
Students explore Beer’s law and calculations that arise from applying Beer’s law.
