This
multi-topic resource covers key spectroscopy techniques used in the analysis of
molecular and atomic systems. The note encompasses a detailed introduction to
electronic spectroscopy, IR spectroscopy, and NMR spectroscopy, including both
proton and carbon types, mass spectrometry, electron spin resonance (ESR), and
Mössbauer spectroscopy. There is also a detailed description of every technique
in its basic principles, experimental setup, and applications in different
fields like chemistry, materials science, and biochemistry. The note also
focuses on how these spectroscopic methods are applied to understand molecular
structures, chemical bonding, and dynamic processes. Perfect for students and
researchers, the book provides both a theoretical background and practical
insights into the more general applications of spectroscopy in modern scientific
research.

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.
This note provides an overview of the principles and applications
of Laser-Induced Breakdown Spectroscopy, a powerful technique for elemental
analysis. Prof. Yalc discusses the physics that underlies LIBS, including the
formation and evolution of laser plasmas, and shows the components of a LIBS
system, including lasers, optics, and detection systems. The note explores
further the use of laser plasma excitation for spectrochemical analysis, which
is applicable to gases, liquids, solids, and particles. A special issue like
double pulse LIBS, resonance-enhanced LIBS, and laser-induced fluorescence (LIF-LIBS)
are also covered. The importance of this note lies in the recent advances and
applications in the areas of materials science as well as environmental
analysis.
