NANSLO Remote Lab Activity: Emission Spectroscopy

This NANSLO lab activity is self-contained and can be used in in general chemistry and survey of chemistry courses. In this activity, the light of different gasses (atomic and molecular) as detected by a spectrometer are used to make connections between electron states and energy levels. It includes background information on spectroscopy -- the student of the interaction between light and matter and, in particular, how atoms or molecules absorb or emit electromagnetic (EM) radiation, and how EM is characterized by its wavelength or its frequency. Included are equations for energy of a photon of electromagnetic radiation and one for the relationship between wavelength and frequency of electromagnetic radiation. The lab activity also includes pre-lab activities and lab activities.
Microsoft Word NANSLO Remote Lab Activity: Emission Spectroscopy uses a spectrometer to identify the most intense peaks in the emission spectra for several molecules and atomic gases, determine the electronic transitions taking place for hydrogen gas and compare them with theoretical predictions using the Rydberg equation, relate wavelength and color of light, and perform other calculations and predictions based on observations during the lab component. It contains pre-lab activities and lab activities. (2 MB)

Quality Note:
Curriculum expert in this discipline worked with Discipline Panel of faculty to define learning objectives needed for this lab activity. During development, teleconferences were held to discuss lab activity being developed. Draft activity was posted to listserv for review by Discipline Panel and other faculty in that discipline. Based on feedback, lab activity was modified prior to posting as final. Experts in remote web-based science labs who are also science faculty worked together to define the web-enabled interface design used by students to perform the lab activity via the Internet and created the lab setup (robotics, scientific equipment, and items needed to complete the lab activity) testing it with lab technicians and others prior to launching the final lab activity.
Quality of Subject Matter was assured by:
  • Consultations during development of instructional materials
Quality of Online/Hybrid Course Design assured by:
  • None
Course Note:
General Chemistry with lab and Survey of Chemistry
