CHEM 342: Physical Chemistry II
Kathryn Davis · Manchester University
Principles of chemical thermodynamics and statistical thermodynamics, with application to pure substances and mixtures. It also applies the principles of chemical kinetics and dynamic equilibrium theory to a variety of chemical applications, including electrochemistry and spectroscopy.

Quantitative NMR
Cynthia K. Larive & Albert K. Korir · University of California, Riverside & Drury University
Quantitative nuclear magnetic resonance (Q-NMR) measurements are especially useful for analysis of complex samples where high specificity is needed or when a pure standard of the analyte is not available. This text provides a brief overview of basic NMR theory, a tutorial discussing the practical aspects of Q-NMR, a virtual experiment utilizing an NMR simulator, an exercise that makes use of real NMR data you can download and analyze, and a Q-NMR lab experiments.

Seven Sketches in Compositionality: An Invitation to Applied Category Theory
Brendan Fong & David I. Spivak · Massachusetts Institute of Technology
Category theory is a relatively new branch of mathematics that has transformed much of pure math research. The technical advance is that category theory provides a framework in which to organize formal systems and by which to translate between them, allowing one to transfer knowledge from one field to another. But this same organizational framework also has many compelling examples outside of pure math. In this text, we will give seven sketches on real-world applications of category theory.

Plant Breeding Methods
Walter R. Fehr and Walter P. Suza · Iowa State University
This text has been compiled to provide an overview of how plant breeders develop cultivars of plant species. The methods that breeders use depend directly on the type of cultivar used to produce a commercial crop. he four most common types of cultivars are (a) clonal cultivars (b) synthetic cultivars (c) pure-line cultivars and (d) hybrid cultivars. These types of cultivars will be discussed throughout the book, alongside review questions for self-study.

Symmetry
Claire Vallance · University of Oxford
Group Theory is a branch of the mathematical field of algebra. One important application, the theory of symmetry groups, is a powerful tool for the prediction of physical properties of molecules and crystals. It is for example possible to determine whether a molecule can have a dipole moment. Many important predictions of spectroscopic experiments (optical, IR or Raman) can be made purely by group theoretical considerations.
