精彩书摘

　　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.

前言/序言

　　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 compo 有机化学中的光谱方法（第6版） [Spectroscopic Methodsir Organic Chemistry 6th de] 下载 mobi epub pdf txt 电子书 格式
