The book is famously divided into three parts:
How fluid internal friction scales with temperature. Thermal Conductivity: The molecular transport of heat.
The interdisciplinary reach of the book was widely noted. One review described MTGL as “an essential cross-disciplinary reference for molecular interactions,” and a “unique cross-disciplinary approach provides useful insight for students of chemistry, chemical engineering, fluid dynamics, and a variety of related fields”. The Molecular Theory of Gases and Liquids by
Unlike simpler, ideal gas laws, Hirschfelder provides the Chapman-Enskog theory, which allows for the calculation of transport coefficients (viscosity, thermal conductivity, and diffusion) for non-ideal, real gases. Liquid State Theory
In conclusion, the molecular theory of gases and liquids is a fundamental concept in physical chemistry that explains the behavior of molecules in different states of matter. The theory provides a detailed understanding of the physical properties of gases and liquids, including their thermodynamic properties, transport properties, and intermolecular forces. The book "Molecular Theory of Gases and Liquids" by Hirschfelder, Curtiss, and Bird is a comprehensive textbook on the molecular theory of gases and liquids, and is recommended for anyone interested in gaining a better understanding of the theory.
If you need to calculate the viscosity, thermal conductivity, or diffusion coefficients of a gas mixture, this book contains the fundamental derivations that modern empirical formulas are based on. The Molecular Theory of Gases and Liquids |
This part is one of the book’s most distinctive contributions. It begins with the kinetic theory of dilute gases, providing a detailed derivation of the Boltzmann equation and its solutions. Transport phenomena in dilute gases—including viscosity, thermal conductivity, and diffusion—are treated with reference to Chapman-Enskog theory, which calculates transport coefficients from intermolecular force laws. The book then extends these methods to dense gases and liquids, exploring the behavior of transport properties under conditions where molecules are in close proximity. A later chapter discusses hydrodynamic applications, connecting the molecular theory to continuum fluid dynamics.
In theoretical chemistry and chemical engineering, few textbooks hold as much authority as Molecular Theory of Gases and Liquids (MTGL). Written by Joseph O. Hirschfelder, Charles F. Curtiss, and R. Byron Bird, this monumental work remains the definitive reference for understanding intermolecular forces and transport phenomena.

The book is celebrated for its rigorous derivation of transport properties (viscosity, thermal conductivity, and diffusion) and its treatment of the virial equation of state. Key Pillars of the Theory 1. Intermolecular Forces
The molecular theory of gases and liquids is based on several key assumptions:
It was the first text to bridge the gap between microscopic molecular properties and macroscopic fluid behavior.
