Page 41 falls within Chapter 1 (Nature of the Intermolecular Forces). It likely discusses:

A better copy will show the equations correctly. In the “pdf41” version, you may see:

f(r) = -C6/r^6 - C8/r^8 + ... (with garbled subscripts)

While a clean copy presents: $$ \phi(r) = -\fracC_6r^6 - \fracC_8r^8 - \fracC_10r^10 + \ldots $$

Since I cannot directly share copyrighted files, here are legitimate and high-quality alternatives: Page 41 falls within Chapter 1 (Nature of

Published in 1954 by John Wiley & Sons, Molecular Theory of Gases and Liquids (often called "Hirschfelder, Curtiss, and Bird" or simply the "yellow book") is not merely a textbook – it is a foundational reference. Its 1,280 pages contain the systematic development of the kinetic theory of gases and the statistical mechanics of dense fluids, based on intermolecular forces.

For decades, it has been the go-to source for:

Section 41 (in conceptual numbering) covers: A better copy will show the equations correctly

Without a clear PDF, you will misapply ( \eta_mix ) (viscosity of a gas mixture) by orders of magnitude. A better PDF41 ensures the difference between the square root symbol and the square symbol is crystal clear.

No single book replaces Hirschfelder et al., but for updated theory, pair it with:

You might ask: Why not just use modern MD software (LAMMPS, GROMACS) or NIST databases? While a clean copy presents: $$ \phi(r) =

Because Hirschfelder provides the analytical foundation that software black-boxes hide. When your simulation fails to match experimental vapor-liquid equilibrium (VLE), you turn to Section 8.4 of Hirschfelder to check your ( kT/\epsilon ) versus ( \rho \sigma^3 ) mapping.

Specifically, a "better" PDF41 allows you to:

Modern textbooks give you the formula for viscosity. Hirschfelder gives you the collision integrals (Ω^(2,2)*) as a function of reduced temperature for 11 different potential functions. If you are modeling a real gas mixture—say, CO₂ and CH₄ at high pressure—you need these tables. No other single source compiles them so completely.
