Molecular Spectroscopy Educational Film Light Wave Oscillation Atomic Structure 14344 (1962)

Synopsis

This is a Chem Studies Film, produced by the Chemical Education Material Study for use in its course in chemistry. Molecular Spectroscopy. Collaborators are Dr. Bryce Crawford Junior, Professor of Chemistry and Dr. John Overend, Associate Professor of Chemistry, University of Minnesota. This movie is about molecular spectroscopy. There are in-depth conversations and vivid imagery about how molecules have natural frequencies of vibration and on the understanding of how light waves interact with those molecules. The movie opens with a rainbow to show the spectrum of light. A narrator comes on the screen 1:00. A man uses a prism to create the spectrum of light on a desk 1: 09. A narrator speaks from his desk 1:30. The model of a wave is animated and shows Planck’s constant, 1:50. Waves are used to talk about length or in terms of frequency which are measured in cycles per second 2:30. The disparity in rates for the low and high frequency waves are shown 2:50. The narrator uses an exposure meter to measure the spectrum of light 4:00. How do molecules affect the spectrum? The narrator uses copper sulfate to demonstrate 4:25. The narrator displays a spectrometer 4:48. Parkin Elmer Infraccord Spectrometer, 5:25. A bobber at the end of a fishing line is shown 6:10. A controlled experiment in a pool with waves is used with a metal bobber 6:30. The narrator speaks, 7:15. The narrator stands in front of a blackboard and demonstrates a light wave experiment, 8:07.
