Theoretical Chemistry:
Theoretical Chemistry employs mathematical models and computational methods to understand and predict chemical behavior at the molecular level. It delves into the fundamental principles governing molecular structures, reaction mechanisms, and electronic properties, providing insights into the nature of chemical bonding and guiding the design of new materials.

Inorganic Chemistry: Inorganic Chemistry focuses on the study of non-carbon-containing compounds, including metals, minerals, and salts. Investigating the properties, structures, and reactions of elements and their compounds, inorganic chemistry plays a crucial role in various fields, such as catalysis, materials science, and medicine. Coordination chemistry and organometallic chemistry are sub-disciplines within inorganic chemistry, emphasizing metal-containing compounds and their applications.
