Physical chemistry, is the application of physics to macroscopic, microscopic, atomic, subatomic, and particulate phenomena in chemical systems[1] within the field of chemistry traditionally using the principles, practices and concepts of thermodynamics, quantum chemistry, statistical mechanics and kinetics.[2] It is mostly defined as a large field of chemistry, in which several sub-concepts are applied; the inclusion of quantum mechanics is used to illustrate the application of physical chemistry to atomic and particulate chemical interaction or experimentation.[1]
Physical chemistry is mostly referred to as a macromolecular doctrine, as the majority of the principles on which physical chemistry was founded are composed entirely of macromolecular concepts, such as colloids.[3]
The relationships that physical chemistry tries to resolve include the effects of:
The term "physical chemistry" was probably first introduced by Mikhail Lomonosov in 1752, when he presented a lecture course entitled "A Course in True Physical Chemistry" (Russian: «Курс истинной физической химии») before the students of Petersburg University.
^ abPhysical Chemistry (p3 - "PHYSICAL CHEMISTRY"), states that the field of physical chemistry is concerned with the microscopic and the macroscopic phenomenon which are mostly concerned with thermodynamics, and kinetics; the field of atomic and particulate interaction being included is implied with the inclusion of quantum chemistry.
^Quantum Chemistry (p3 - "PHYSICAL CHEMISTRY"), states that "We can divide physical chemistry into four areas: thermodynamics, quantum chemistry, statistical mechanics and kinetics".
^Physical Chemistry of Macromolecules (p1 - "INTRODUCTION"), defines the formation of physical chemistry as being between macromolecules and colloids in modern physical chemistry. Also defines the "fierce battles" in the 1900s between the inclusion of colloids AS macromolecules.
