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.
This note aims to have a detailed
explanation of Nuclear Magnetic Resonance (NMR) spectroscopy focusing on its
applications in the study of molecular structure, especially proteins and other
biomolecules. Key topics explored include the electromagnetic spectrum, the
vector model of NMR, magnetization properties, and NMR excitation. The note
further introduces advanced concepts like chemical shift, nuclear shielding, and
spin-spin coupling as all forms necessary for interpreting NMR spectra. There
have been introductions of multi-dimensional NMR techniques that use them in
protein structure determination, and this book is very useful for researchers
and students to understand the theoretical and applied aspects of NMR
spectroscopy.
