It is an
introductory note focused on key concepts in atomic and molecular spectroscopy,
which serves as a foundational understanding of several types of spectroscopic
techniques, which include atomic spectroscopy, molecular spectroscopy, and then
more specialized techniques such as rotational, vibrational, Raman, and
electronic spectroscopies. The note goes into principles and applications to how
they are used in studying the structure and behavior of molecules and atoms.
This help resource will be valuable to students and beginners interested in
understanding the theory behind spectroscopic techniques as applied in chemical
analysis, materials science, and molecular studies.
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.
