Physical chemistry is the study of macroscopic, atomic, subatomic and particle phenomena in chemical systems in terms of principles, practices and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, Analytical dynamics and chemical equilibrium.
Physical chemistry, in contrast to chemical physics, is predominantly (but not always) a macroscopic or supra-molecular science, since most of the principles on which it was founded are related to mass and not just to molecular structure / Atomic, chemical equilibrium and colloids).
Physical chemistry has traditionally given students extensive training, and has positioned them to work in a variety of scientific careers. Many people trained as physical chemists ultimately work as analytical chemists, where they work to understand the fundamental process involved in analytical techniques, allowing them to improve and expand those techniques.
For example, Matt Lynch, senior scientist at the Procter & Gamble Beauty Care Division, works in physical / analytical chemistry, conducting applied and basic surfactant investigations for product development applications. Their job is to observe the set of molecules and determine how to measure and quantify them. Lynch says, "We assemble molecules into crystals and solutions and we look at how to measure that in terms of arrangements of atoms and molecules, how they grow to form larger aggregates in both solutions and crystals, and how these aggregates of surfactants impart various properties to a" . Lynch points out that he uses diffraction, infrared and microscopy methods in his work. By developing better ways to measure and quantify aspects of ingredients, it helps your company develop better products.
