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.
NIST Chemistry WebBook
From web pages "The NIST Chemistry WebBook" provides access to data compiled and distributed by NIST, giving access to Thermochemical data for over 7000 organic and small inorganic compounds; Reaction thermochemistry data for over 8000 reactions; IR spectra for over 16,000 compounds; mass spectra for over 15,000 compounds; UV/Vis spectra for over 1600 compounds; electronic and vibrational spectra for over 4500 compounds; constants of diatomic molecules (spectroscopic data) for over 600 compounds; ion energetics data for over 16,000 compounds; thermophysical property data for 34 fluids.
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.
