Mass spectrometry has played an integral part in the study of organic molecular structures for more than 50 years, offering significant information from small amounts of sample. The mass spectrum produced by electron impact ionization presents a pattern of peaks that can often give definitive structural information about an unknown compound. Introductory Mass Spectrometry, Second Edition guides readers in the understanding and recognition of those patterns, discussing mass spectra in terms that are familiar to chemists. It provides a basis for chemists to interpret mass spectra to solve particular structural problems.The Second Edition has been updated with modern techniques and data handling. Beginning with an introduction to the principles and instrumentation, it then sequentially explains the processes that occur in the mass spectrometer following ionization. The book is unique in the large number of mass spectra presented and provides examples of mass spectra from a wide variety of organic chemicals, concentrating on the relationships between fragmentation patterns, common chemical reactions, and chemical structures. The book also discusses mass spectra obtained with softer ionization techniques, which provide definitive information regarding molecular weights.The text describes mass spectra produced by electron ionization, discussing how the spectral peak pattern relates to molecular structure. It details the use of high-resolution and accurate mass measurement to determine elemental composition of ions in order to identify unknown substances. The book also introduces some of the recent techniques that can be employed to extend the usefulness of mass spectrometry to high molecular weight substances and more polar substances. It includes examples and problems representing a cross section of organic chemistry to help readers integrate the principles presented.

The study of insurgency and counterinsurgency over the years provides a valuable tool for analysis in the current Global War on Terrorism. Failure to take into account and accurately assess political and military actions in such environments can lead to unintended consequences (potential civil war) affecting the stability of a country. Accurate assessment of the political and military actions does not guarantee success or failure, as every insurgency is a unique case, which requires observation and analysis through the strategic implications particular to each circumstance. One historical example for analysis is the British Military Mission (BMM) to Greece in 1942-44, which begs the question 'did the policies utilized by the British in balancing the opposing political and military objectives of rival guerilla forces delay or help bring about the Greek Civil War?'; This monograph explores the question by analyzing the historical documentation of actual events that transpired during the mission and whether they delayed or help bring about the Greek Civil War. The British Military Mission to Greece from 1942-44 originated for the purpose of disrupting German supply lines to North Africa in support of British operations aimed at defeating the Germans at El Alamein. This twelve-man mission inserted into Greece to organize, coordinate and direct Greek guerilla factions against occupying Axis forces and sever crucial supply lines feeding German forces in North Africa. The initial target consisted of a viaduct supporting the single rail line running through the country. The British members of the mission in coordination with two rival guerilla factions successfully destroyed the viaduct and halted German supply flow for several weeks. The mission demonstrated that guerilla forces in conjunction with Allied support could accomplish critical missions tied to Allied strategy and opened the door for more ambitious plans for coordinated guerilla warfare throughout Europe.
