Chemical physics is a subdiscipline of
chemistry and
physics that investigates physicochemical phenomena using techniques from
atomic and molecular physics and
condensed matter physics; it is the branch of physics that studies chemical processes from the point of view of physics. While at the interface of
physics and
chemistry, chemical physics is distinct from
physical chemistry in that it focuses more on the characteristic elements and theories of physics. Meanwhile, physical chemistry studies the physical nature of chemistry. Nonetheless, the distinction between the two fields is vague, and workers often practice in both fields during the course of their research.
