Atkins' Physical Chemistry epitomises the benchmark of achievement for a chemistry degree throughout the world. Its broad coverage, concise explanations, and robust mathematical support are clearly presented in an engaging style to furnish students with a solid foundation in the subject. In this ninth edition the authors continue to refine their presentation of physical chemistry. The coverage of introductory topics is streamlined, and the addition of a new fundamentals chapter provides students with an overview of key principles on which the subject is based. The text includes increased coverage of computational chemistry and additional contextual examples of materials chemistry throughout, mirroring the current needs of today's students and lecturers. Mathematics remains an intrinsic yet challenging part of physical chemistry. Extensive mathematical support, including a 'Checklist of key equations' at the end of every chapter, and 'Mathematical background' sections containing worked examples and self-tests, empower students to overcome any barriers to understanding that grasping the mathematical content might present. These features help to ensure the reader can master the subject without a need to sacrifice the rigour and depth of the mathematical content. The pedagogical framework, which is a hallmark of the authors' writing, has been further strengthened. New 'Key points' provide summaries of the main take-home messages of each section and enable students to gain an overview of the topic before tackling it in depth; 'Brief illustrations' give a concise insight into how a particular mathematical concept is applied in practice, providing students with the opportunity to contextualise their learning. All these exciting new features and innovations are presented within a refreshed full colour text design, to stimulate and engage students yet further. The Online Resource Centre contains Living Graphs, illustrations from the book, and web links. An Instructor's Solutions Manual (free to adopters) and a Student's Solutions Manual are also available. Access to the Physical Chemistry eBook is also included with the purchase of the printed text. Offering enhanced functionality, including notetaking and highlighting, it also includes access to 'Explorations in Physical Chemistry', which contains interactive Excel worksheets and exercises related to the Living Graphs, allowing students to visualise, actively explore and test their understanding of the subject.
