有機化學中的光譜方法
前言
This book is the sixth edition of a well-established introductory guide to the interpretation of the ultraviolet, infrared, nuclear magnetic resonance and mass spectra of organic compounds. It is a textbook suitable for a first course in the application of these techniques to structure determination, and as a handbook for organic chemists to keep on their desks throughout their career.   These four spectroscopic methods have been used routinely for several decades to determine the structure of organic compounds, both those made by synthesis and those isolated from natural sources. Every organic chemist needs to be skilled in how to apply them, and to know which method works for which problem. In outline, the ultraviolet spectrum identifies conjugated systems, the infrared spectrum identifies functional groups, the nuclear magnetic resonance spectra identify how the atoms are connected, and the mass spectrum gives the molecular formula. One or more of these techniques nowadays is very frequently enough to identify the complete chemical structure of an unknown compound, or to confirm the structure of a known compound. If they are not enough on their own, there are other methods that the organic chemist can turn to: X-ray diffraction, microwave absorption, the Raman spectrum, electron spin resonance and circular dichroism, among others. Powerful though they are, these techniques are all more specialised, and less part of the everyday practice of most organic chemists,We have kept discussion of the theoretical background to a minimum, since application of the spectroscopic methods is possible without a detailed command of the theory behind them. We have described instead how the techniques work, and how to read each of the four kinds of spectra, including each of the most important 2D N-MR spectra. We have included many tables of data at the ends of Chapters 2, 3 and 4, all of which are needed in the day-to-day interpretation of spectra. Finally in Chapter 5, we work through 11 examples of the way in which the four spectroscopic methods can be brought together to solve fairly simple structural problems, and there are 33 problem sets for you to work through for practice.In preparing a sixth edition, we have almost completely rewritten the book, to reflect our experience teaching the subject, and to respond to changes that have taken place, both of emphasis and of fact, since the fifth edition was published. The chapters on UV and IR spectra are more concise, the chapter on NMR is expanded, and the chapter on MS made more specific to the everyday, rather than to the more specialised, applications of this technique. The appearance of IR absorptions, formerly gathered at the end of the chapter, are now illustrated at the relevant points in the text. Conversely, we have moved the tables of IR data to the end of the chapter, where they are more convenient for reference, and match the arrangement we have always used for the NMR and MS chapters. Most significantly, we have replaced all of the 60 MHz spectra used hitherto to explain the fundamentals of NMR spectroscopy with new and carefully chosen examples at 400 MHz or more. We have also chosen several new compounds with which to illustrate better the common 2D NMR techniques.
内容概要
  本書是一本由英國劍橋大學D. H. Williams和I. Fleming合著的有機化學光譜方法經典教材。第1版出版于1966年,本書為第6版。書中講述了近年來迅猛發展的二維核磁共振(如Tocsy、遠‘H-13C COSY)、MALDI、FT-ICR、TOF等新技術。與時俱進,本版較前版在內容上做了較大的改動,有關UV和IR光譜的部分講述的更加準確;豐富了關于NMR的內容;介紹MS的部分更加講求結合實際。全書共分為五章,第1章為紫外和可見光譜,論述了電子吸收光譜在測定有機基團中的應用;第2章紅外光譜,闡述了傅里葉紅外和喇曼光譜的樣品制備、光譜選律以及各官能團的特征吸收頻率;第3章核磁共振波譜,主要介紹了‘H和13C核磁共振的經驗參數、各種二維NMR的具體應用;第4章質譜,介紹了各種粒子譜以及氣相和液相色譜與質譜的聯用;第5章實例和習題,為讀者提供了一些選自研究課題、具有啟發性的實例,也為讀者鞏固所學的知識提供了練習。本書理論和實踐並舉,因此也適合有機化學工作者做為手冊使用。  讀者對象︰高校化學系師生、有關研究人員。

章节摘录
插圖︰The energy absorbed by the matrix is transferred indirectly to the sample, which reduces any sample decomposition. The matrix is chosen to have solubility properties similar to those of the sample, in order that the sample molecules are properly dispersed. Higher molecular weight oligomeric 'clumps' are produced as 2M+, 3M+, and so on, but these are usually minor components of the spectrum if a well-matched matrix is chosen.   4.3.3 Electrospray ionisation (ESl) An 'electrospray' is the term applied to the small flow of liquid (generally 1-10 lxl/min) from a capillary needle when a potential difference typically of 3-6 kV is applied between the end of the capillary and a cylindrical electrode located 0.3-2 cm away (Fig. 4.4). The liquid leaves the capillary as a fine mist at or near atmospheric pressure, and consists of highly charged liquid droplets. The charge on these droplets may be selected as positive or negative according to the sign of the voltage applied to the capillary. ESI is especially useful since it can be used to analyse directly the effluent from an HPLC column.The use of a 'sheath' gas or 'nebulising' gas promotes efficient spraying of the solution of the sample from the capillary. Sample molecules dissolved in the spray are released from the droplets by evaporation of the solvent. This evaporation is accomplished by passing a drying gas across the spray before it enters a capillary. As the droplets are multiply charged, and reduced in size by evaporation, the rate of desolvation is increased because of repulsive Coulombic forces. These forces eventually overcome the cohesive forces of the droplet, and an MH~ (or M - H+) molecular ion free of solvent is finally produced. The charged particles are carried, by an appropriate electric field, through a capillary and into an ion analyser.

评论与打分
  •     我們大學的波譜課老師,就是幾乎全部參考這本書去做英語的ppt的。
    里面的內容對于初學者來說非常全面系統,有介紹到二維譜的知識,也有說到各種光譜學現象的解釋,又不會有過多數理推導過程,實在值得購買!
  •     英文的,有點看不懂,可是這本應該是解譜的權威書
  •     看原版的比看翻譯的(北京大學出版社的)更明白
    英文影印版的只要59(原價),肯定比原版書便宜多了
  •     同事出差,還未開封哦
  •     大概瀏覽了一下,第一印像是圖和數據佔了很大的篇幅,如果是想查數據的話,我推薦瑞士petsch寫的《波譜數據表︰有機化合物的結構解析》。《有機化學中的光譜方法》對方法的介紹只能算是簡單的介紹,本來文字就不多,對相關儀器的原理和測試過程沒有涉及,制樣方法和注意事項也沒有。這本書可以幫助學會解譜,但是想要完成一個完整的實驗,光靠這本書是不夠的。
  •     英文版,非專業出生,連蒙帶猜
  •     全英文的,印刷還好,影印版的雖然相對國外原版的便宜,但相對這個厚度還是比較貴了。
  •     作為譜學導論的基本英文教材,已經相當不錯了。
  •     還沒看,不過書的質量很好,且活動後的價錢相當給力
