Computational Spectroscopy of Polyatomic Molecules
CRC Press (Verlag)
978-1-032-43372-1 (ISBN)
The book addresses key aspects of the high-accuracy computational spectroscopy of the medium size polyatomic molecules. It aims to describe numerical algorithms for the construction and solution of the nuclear motion Schrödinger equations with the central idea of the modern computational spectroscopy of polyatomic molecules to include the construction of the complex kinetic energy operators (KEO) into the computation process of the numerical pipeline by evaluating the corresponding coefficients of KEO derivatives on-the-fly. The book details key aspects of variational solutions of the nuclear motion Schrödinger equations targeting high accuracy, including construction of rotational and vibrational basis functions, coordinate choice, molecular symmetry as well as of intensity calculations and refinement of potential energy functions. The goal of this book is to show how to build an accurate spectroscopic computational protocol in a pure numerical manner of a general black-box type algorithm.
This book will be a valuable resource for researchers, both experts and not experts, working in the area of the computational and experimental spectroscopy; PhD students and early-career spectroscopists who would like to learn basics of the modern variational methods in the field of computational spectroscopy. It will also appeal to astrophysicists and atmospheric physicists who would like to assess data and perform calculations themselves.
Key features:
Supported by the latest research and based on the state-of-the-art computational methods in high-accuracy computational spectroscopy of molecules.
Authored by an authority in the field.
Accessible to both experts and non-experts working in the area of computational and experimental spectroscopy, in addition to graduate students.
Sergey Yurchenko is a Professor of Physics in the Department of Physics and Astronomy at University College London (UCL), UK. He gained his PhD from Tomsk State University, Russia, in 1997 on the subject of molecular spectroscopy. He worked as a research associate with Per Jensen and Phillip Bunker, authors of the leading textbook on molecular symmetries. Prof. Yurchenko is an author of the open-source codes TROVE and Duo, which are among the main tools of today’s computational spectroscopy and are used by the ExoMol project for building a database of opacities for molecules important for atmospheres of exoplanets and cool stars. Since 2011 he has been a member of staff of at UCL where he lectures and supervises Master's and PhD students.
