Structure Determination Using Spectroscopic Methods
This note
focuses on how spectroscopic techniques can be integrated to determine the
structure of unknown molecules. It starts off with an overview of the
electromagnetic spectrum and basic 1H NMR, moving on to much advanced discussion
about how NMR can be combined with other methods such as IR, UV, and mass
spectrometry for an overall structural analysis. It goes over chemical shifts of
protons, coupling constants, and the use of 2D NMR for obtaining detailed
structural information. Other topics discussed include multinuclear NMR, dynamic
NMR and conformational, as well as chemical exchange rates measurement. This
note is perfect for students and researchers who want to use several
spectroscopic methods in the determination of the structure of a compound.
James Keeler's note on NMR spectroscopy is rather solid in presenting
principles of NMR along with its application to chemical structure analysis. It
covers key topics like energy levels involved in NMR, the vector model, Fourier
transformation, and data processing. The note explains how NMR spectrometers
work and introduces more advanced techniques like two-dimensional NMR, which
permits the analysis of far more detailed complex molecular structures.
Additional topics covered include relaxation processes, phase cycling, and
gradient pulses to give a full understanding of NMR spectroscopy to students and
researchers looking to master this powerful analytical tool.
