Computational Chemistry is a very welcome book whose main qualities are the rigour and the completeness achieved without sacrificing the synthesis. * Antonio Monari, Universite de Lorraine, Acta Cryst. (2018) C74 * This short and easily readable book provides an excellent guide to the world of computational chemistry. It could be successfully used also by graduates, students or researchers from the experimental chemistry fields, who seek a general, yet critical, view of the possibilities offered by modelling and simulation. * Antonio Monari, Universite de Lorraine, Acta Cryst. (2018) C74 * Significantly, one of the strengths of the book is the constant use of real-life examples in the form of real calculations performed by the author, which students are encouraged to repeat, to illustrate the different methods and the different problems. * Antonio Monari, Universite de Lorraine, Acta Cryst. (2018) C74 * A valuable and productive effort that can strongly benefit the development and the general understanding of computational chemistry and molecular simulation. * Antonio Monari, Universite de Lorraine, Acta Cryst.
