· Understand principles behind IR Spectroscopy as it relates to the stretching & bending of bonds
· Observe the inverse relationship between vibrational frequency and bond length
· Analyze spectra to predict functional groups and bonds in an organic molecule
· Understand the role resonance plays in vibrational frequencies
· Observe effects on sample preparation on quality of spectra
Exp 4 Pre-lab quiz - take on Canvas if you haven't already
Submit the Worksheet individually on Canvas at the end of lab
Remote students: Participation during your enrolled section - tracked by Zoom polls - contact your TA immediately if you are / were unable to attend and we'll make other arrangements
Contribute to the Experiment 4 Canvas Discussion
You and your partner complete the lab report (IR tables & in-lab question, and problem set) together per your Partner Agreement
Full details in the Exp 4 PDF on Canvas
Submit on GradeScope as a pair one week after doing the remote lab - due at enrolled lab start time - instructions are on Canvas
