The Visible Spectrum of Liquid Oxygen in the General Chemistry Laboratory
Frazier Nyasulu, John Macklin, and William Cusworth III
Department of Chemistry, University of Washington, Seattle, WA 98195-1700

March 2002
Vol. 79 No. 3
p. 356
Abstract
General chemistry experiments that address one or more aspects of molecular orbital theory are scarce. The measurement and interpretation of the visible spectrum of liquid oxygen fills this gap and extends molecular orbital theory described in the typical course. With some guidance from the instructor, students test three energy-level diagrams (hypotheses) to find the one that fits the measured spectrum.

Hazard: Liquid oxygen poses a safety hazard. See J. Chem. Educ. 2003, 80, 486.
