Physical chemistry is the study of the physical basis of chemical systems and processes. Modern physical chemistry is firmly grounded upon physics. Important areas of study include chemical thermodynamics, chemical kinetics, quantum chemistry, statistical mechanics, electrochemistry, surface and solid state chemistry, and spectroscopy.

NMR Spectroscopy. Principles and Application
Six second year lectures given at Imperial College by Henry Rzepa. Overview of NMR spectroscopy including principles of Nuclear Magnetic Resonance, applications of 13C NMR and applications of 1H NMR.
The NIST Reference on Constants, Units, and Uncertainty
This site addresses three topics: fundamental physical constants, the International System of Units (SI), which is the modern metric system, and expressing the uncertainty of measurement results. Both essential information and background information are given for each topic.
The Second Law of Thermodynamics
Comprehensive and qualitative discussion of the Second Law of Thermodynamics, the law introducing entropy change as a driving force for spontaneous processes.
