Molecular Structure and Absorption Spectra
Thursday, 15 May, 2025
In this episode, we cover molecular structure and the key spectroscopy techniques you need to know for the MCAT. We'll explore the intricacies of Nuclear Magnetic Resonance spectroscopy, breaking down the chemical shifts and spin-splitting essentials for understanding hydrogen and carbon bonds in various compounds. You'll learn how to identify functional groups using Infrared (IR) spectroscopy and how mass spectrometry can help determine molecular weights and identify unknown compounds. We'll also touch on UV-Vis spectroscopy and its role in quantifying compounds based on absorption spectra. Visit MedSchoolCoach.com for more help with the MCAT.
