at (202) 227-5558, press 82. Be sure to specify that you are registering for the Southwest Regional Meeting public relations workshop. A workshop on nuclear magnetic resonance workbench and protein modeling software will be run by Don Gregory of Molecular Simulations. The NMR workbench program, scheduled for Thursday morning, is designed to facilitate the assignment of resonances in multidimensional NMR spectra. The protein modeling program on Thursday afternoon will assist chemists in the design and analysis of protein structures by using a variety of approaches. Both workshops will offer introductions to the programs and hands-on experience with software using Silicon Graphics workstations. Enrollment will be limited to about 22 participants per workshop, so registration will be on a firstcome, first-served basis (see registration form).

Spectroscopy off Polymers by JACK L KOENIG Department of Macromolecular Science Case Western Reserve University
f*j|^f^wf
A
t last—the definitive resource for scientists, engineers, and graduate students in polymer science on the primary spectroscopic methods of polymer characterization that continues where introductory-level texts end.
Spectroscopy of Polymers was written for those whose knowledge of polymer chemistry includes some familiarity with the basic vibrational and resonance spectroscopic methods, but who have limited experience in applying the modern techniques of FTIR, Raman, and/or NMR spectroscopy. The book provides a solid background in the fundamental aspects and experimental applications of the primary spectroscopic methods and their advantages and disadvantages for particular polymer systems. It brings both professional and student up-to-date on the current techniques and facilitates communication with others in the field. Throughout the eleven chapters of this book, Koenig provides clear, concise examples to demonstrate the strengths and weaknesses of the various vibrational and NMR techniques and offers the reader practical knowledge of how to select the most appropriate solutions to polymer structure problems. Numerous illustrations accompany both text and examples. ABOUT THE AUTHOR Jack Koenig is the J. Donnell Institute Professor of the Departments of Macromolecular Science and Chemistry at Case Western Reserve University, Cleveland, Ohio, and has over 25 years teaching and research experience to his credit. He has published over 430 papers, edited or authored 5 monographs, and has won numerous awards, among them the prestigious Pittsburgh Scpectroscopy Award, the New York Society of Spectroscopy Gold Medal, the Society of Plastics Engineers Research Award, the ACS Doolittle Award.

Continued from page 57 sampling design, quality assurance procedures, and analytical protocols for each project listed in the plan. In a letter to the House Appropriations Committee, ACS charges that a plan to let PTO spend $11 million less than the amount it collects in user fees— effectively forcing it to realize a profit on its operations—would send a message to other federal agencies that fiscal responsibility will only lead to further reductions of their budgets. And it points out that the longer review times or higher fees for patent applications that would result from lower PTO funding would impede the marketing of new products and the government's receipt of tax dollars from their sale.
