Preface

Since the publication of Vibrational Spectra of Organometallic Compounds in 1977, there have been no other books published that deal exclusively with this topic. There have, however, been many more studies that have included vibrational data dealing with organometallic compounds. These have often used a range of more recently developed spectroscopic techniques that have provided information not easily obtained using traditional infrared and Raman spectroscopy. Also, the use of density functional theory (DFT) calculations has now become routine in analyzing and assigning experimental data, determining the structures of experimentally prepared materials, and predicting spectra for compounds that have not yet been prepared. And there have now been many studies of the vibrational spectra of organic species that form on metal surfaces that were not common when the original work was published. The study of the vibrational spectra of organometallic compounds therefore remains an active and fruitful field of research.

It therefore seemed appropriate and timely to prepare another expanded book to update the material available on the topic. Although the goal was to include all relevant work, I am sure, because of the number of available studies, that I have probably omitted some important work, and for this I apologize. As with the original book, this new work is divided into three parts. Part I treats organometallic compounds and species on metal surface with saturated organic groups. Part II deals with organometallic compounds and species on metal surfaces that are unsaturated and noncyclic. And Part III reviews material on organometallic compounds and organic species on metal surfaces that are unsaturated and cyclic.

This new work has been a long time coming since my teaching and other duties at Loras have received most of my focus since the first work was completed. These responsibilities have been very fulfilling, and I am very thankful for the supportive and stimulating environment that Loras has provided for the bulk of my professional career. As that phase of my life began to finish, however, I thought it was appropriate to complete this book. There are many to thank who have aided in this endeavor. One of my initial inspirations was the late Professor Kazuo Nakamoto who not only guided me through my graduate school years but also continued to inspire me as he maintained his passion for his work even after his retirement. There has also been the collegial support from my colleagues in the Chemistry Program at Loras who have always impressed me by their professionalism and genuine interest in the education and personal well‐being of our students. I also must thank the interlibrary loan staff at Loras who were always successful in finding an article that I requested, no matter how obscure. Of course, my wife Gerry has also been supportive not only during my teaching career but also more recently as I have spent much time working on this project.
