Course Overview
This course explores various spectroscopic techniques essential for chemistry research, including elemental analysis, mass spectrometry, infrared spectroscopy, UV-Visible spectroscopy, Raman spectroscopy, and nuclear magnetic resonance (NMR). A special focus is placed on advanced NMR methods like COSY and HSQC, highlighting their role in determining molecular structures. The curriculum emphasizes hands-on experience, teaching students to operate spectroscopic instruments and use data analysis software.
Lectures cover theoretical foundations and analytical approaches for interpreting spectroscopic data to deduce the structures of complex organic compounds. This course builds upon concepts from previous chemistry classes, aiming to provide an engaging and practical learning experience.
The instructors are committed to supporting student learning and welcome feedback to enhance the course. Students are encouraged to engage with the teaching team for any course-related discussions.
Spectroscopy plays a crucial role in both academic and industrial settings, particularly in the analysis and identification of synthesized materials. The problem-solving and analytical skills developed through complex structural elucidation exercises have applications beyond the field of chemistry.
