fysiskkjemiske

Fysiskkjemiske is a Norwegian term used to describe the study of the physical properties and processes of chemical systems. It is closely related to physical chemistry and denotes the use of physical principles to understand how matter behaves, reacting and changing under different conditions of temperature, pressure, and composition.

The field encompasses a range of core topics, including thermodynamics, kinetics, quantum chemistry, spectroscopy, phase equilibria, and transport phenomena. It addresses how energy changes accompany chemical reactions, how molecular structure influences behavior, and how macroscopic properties emerge from microscopic interactions. Fysiskkjemiske approaches are applied to liquids, solids, polymers, and interfaces, as well as to complex systems such as solutions and catalysts.

Common methods in fysiskkjemiske research include calorimetry to measure heat changes, various spectroscopic techniques (such as infrared, UV-visible, and nuclear magnetic resonance) to probe structure and dynamics, and computational modelling based on quantum mechanics and statistical mechanics. Experimental and theoretical tools are often combined to predict material properties, reaction mechanisms, and performance under real-world conditions.

Applications span materials science, catalysis, energy storage and conversion, environmental science, and pharmaceutical development. The term is also used to describe fysiskkjemiske egenskaper (physical-chemical properties) of substances, such as thermodynamic stability, solubility, conductivity, and reactivity, which are critical for design and analysis in science and engineering.
