(chemistry) The study of the effects of isotopic substitution on chemical compounds, especially on the kinetics of their reactions.

(chemistry) the chemistry of organometallic compounds; their preparation, structure and reactions

(chemistry) The chemistry of organic compounds (that is, chemical compounds with carbon atoms in a covalent bond).

(chemistry, physics) The science that uses theories and techniques from physics to study chemical systems.

(chemistry) The synthesis of a large number of structurally related compounds, especially in the pharmaceutical industry in an attempt to produce improved drugs.

(chemistry) the chemistry of coordination compounds

(chemistry) The application of chemical techniques to the solution of problems in nuclear physics, including the discovery of naturally occurring and synthetic radioactive elements and the results of nuclear fission.

(physics, chemistry) The study of the chemical changes that result from the absorption of ionizing radiation.

(chemistry, physics) the application of quantum mechanics to chemical problems

(informal, chemistry) Any of the traditional methods and techniques of chemistry, especially those of analytical chemistry that use gravimetric analysis or volumetric analysis rather than spectroscopy.
