Ред 1:
'''Teoretska hemija''' objašnjava hemijska i fizička opažanja. Teoretska hemija koristi fundamentalne zakone fizike, [[Kulonov zakon]], [[kinetička energija|kinetičku energiju]], [[Potencijalna energija|potencijalnu energiju]], [[Virijalna teorema|Virijalnu teoremu]], [[Plankov zakon]], [[Паулијев принцип|Paulijev princip isključenja]] i mnoge druge, u objašnjavanju i predviđanju hemijskih fenomena. Termin [[kvantna hemija]], koji potiče od Borovog kvantizovanog modela elektrona u atomu, primenjuje vremenski nezavisne [[Ервин Шредингер|Šredingerove]] i vremenski zavisne [[Пол Дирак|Dirakove]] formulacije.<ref>-{Attila Szabo and Neil S.

U opštem slučaju potrebno je praviti razliku između teoretskog pristupa (nivoa teorije poput [[Metod Hatri-Foka|Hartri-Fok]] (HF), [[Spregnuti kluster|spregnutog klastera]], relativistike, etc.) i matematičkog formalizma,: [[ravanski talas|ravanskog talasa]], [[Сферни хармоници|sfernih harmonika]], periodičnog potencijala [[Blohov talas|Blohovog talasa]]. Metodi koji iterativno rešavaju energije (svojstveni vektori) [[stacionarno stanje|stacionarnog stanja]] talasa obuhvataju: ograničeni Hatri-Fok (RHF), [[multi-konfiguraciono samosaglasno polje]] (CASSCF ili MCSCF), mada se teorija odnosi na Šredingera. <!--Related areas in theoretical chemistry include the mathematical characterization of bulk materials (e.g. the study of [[electronic band structure]] in [[solid state physics]]) using the theory of [[Electronic band structure]] in a Periodic Crystal Lattice. Different theoretical approaches are [[Molecular mechanics]] and Topology. The study of the applicability of well established mathematical theories to chemistry is crucial to metals (i.e. topology in the study of small bodies explains the elaborate electronic structures of clusters). This later area of theoretical chemistry originates from the so-called [[mathematical chemistry]]. Time Dependent Quantum Molecular Dynamics, is a modern approach to the interaction of light with molecules that vibrate and drive reactions in a desired direction.-->
