chemical physics
An interdisciplinary field combining chemistry and physics, focusing on physicochemical phenomena.
Chemical physics is a discipline that studies the boundary area between chemistry and physics.
物理化学 (physical chemistry) is closely related but often emphasizes the application of physics to chemical systems, while 化学物理学 (chemical physics) may focus more on chemical approaches to physical phenomena. The distinction is subtle and sometimes used interchangeably.
Compound of 化学 (かがく, 'chemistry') and 物理学 (ぶつりがく, 'physics').
