In the course of the development of surface science, advances have been identified with the introduction of new diagnostic probes for analytical characterization of the adsorbates and microscopic structure of surfaces and interfaces. Among the most recently de veloped techniques, and one around which a storm of controversy has developed, is what has now been earmarked as surface enhanced Raman scattering (SERS). Within this phenomenon, molecules adsorbed onto metal surfaces under certain conditions exhibit an anomalously large interaction cross section for the Raman effect. This makes it possible to observe the detailed vibrational signature of the adsorbate in the ambient phase with an energy resolution much higher than that which is presently available in electron energy loss spectroscopy and when the surface is in contact with a much larger amount of material than that which can be tolerated in infrared absorption experiments. The ability to perform vibrational spectroscopy under these conditions would lead to a new understanding about the chemical identity, geome try, and bonding of adsorbed material at a level previously unacces sible. It is for these reasons that the last few years have brought an explosion of activity surrounding the exploitation of SERS. The search for the origines) of the anomalous enhancement has given rise to a research sub-activity of its own. Efforts to explain the en hancement have led to an increased understanding of the whole range of phenomena associated with the interaction of photons with adsor bates and metal surfaces."

This book is designer for students who hav had three terms of Chinese and want to read something to reinforce their vocabulary, while at the same time enjoying a modern style novel.

This second book of the Read Chinese series covers an additional three hundred Chinese characters, in both simplified and traditional forms. It is structured within the framework of a story about a Chinese student's journey to Beijing. The text uses both pinyin and Yale romanization where appropriate, and includes writing and stroke order charts.

Written with the two-fold purpose of increasing proficiency in the language and affording an insight into Chinese civilization, this unusual book has lectures on such varied subjects as the people and culture of China, the geographical environment, the history, traditional and present government, the traditional agricultural economy, contemporary agriculture and industry, and Chinese literature, language, and philosophy. Each of the twenty lectures is divided into six parts: vocabulary, romanized version of the lecture, character version, phrases and sentences for translation from Chinese to English and from English to Chinese, and questions. The book introduces approximately 1,070 vocabulary items, all in the Yale romanization, each lecture averaging 55 new items carefully woven in with the old ones in the phrases and sentences for translation. There are two kinds of questions: those based on the text and those leading to a general discussion of Chinese culture.Prepared under contract with the U.S. Office of Education, the book has been treated in classrooms since 1963, Two volumes. Yale Linguistic Series.Mr. Huang is an instructor at the Institute of Far Eastern Languages, Yale University, and the collaborators were also at Yale during preparation of the book.

This third book of the Read Chinese series covers an additional four hundred Chinese characters, in both simplified and traditional forms. The selections are drawn from modern narrative and expository prose, as well as plays and other materials. The text uses Yale romanization and traditional characters only.
