What This Document Is
This is a POGIL (Process Oriented Guided Inquiry Learning) activity designed to accompany an introductory biochemistry course, specifically focusing on the historical foundations and practical applications of spectroscopy. It centers around a seminal article by Stokes (1864) and explores the relationship between light, energy, and molecular structure. The activity is intended to be completed collaboratively, encouraging students to actively engage with the material and develop their problem-solving skills.
