文档介绍：Preface to the second edition How time flies! How rapidly things change! It is hard to believe that the first edition of Spectroscopy of Polymers is not only out of date but also out of print. Therefore, I took the opportunity to rewrite major sections of the book in an effort to bring in the large number of recent advances in the spectroscopy of polymers. The challenges of characterizing the molecular structure of synthetic polymers continue to grow as the polymer chemists for a broad range of new materials applications are synthesizing exciting new structures. The first chapter on the theory of polymer characterization is essentially unchanged with only minor editions and tightening of some of the text. The second chapter has been substantially modified to include both Raman and Infrared in the description of the molecular basis of vibrational spectroscopy. This makes for a more consistent approach and will better guide the student to the more subtle differences in the applications of the plementary methods of vibrational spectroscopy. The chapter on infrared instrumentation and sampling techniques has been modified to include innovations in instrumentation such as step-scan and focal array detector imaging interferometers. The sections in this chapter on data processing and quantitative analysis have been updated to reflect the major impact in this field of fast computers with large memories. The chapter on applications of infrared has been updated by including some of the new developments in the continuing astronomical growth in the applications of infrared to polymers. It is possible to include only a small number of the numerous new examples that are available and those selected were based on the utility as pedagogical examples for the student. Raman spectroscopy has e a most important tool for characterization of polymers as low frequency lasers have improved so Raman spectroscopy excited in the infrared frequenc
