Another survey may be made based on the presence of an explosive atomic group. This survey is helpful for substances not specifically described in Bretherick s book. A table of atomic groups characteristic of explosive substances is presented on page XXXViii of the handbook or on page 42 of Safety of Reactive Chemicals 3. If the explosive atomic group is contained within a substance in question, the substance is probably explosive and it should be treated very carefully. Some companies that have already conducted preliminary evaluations of reactive chemicals will add the atomic group specific to unstable new substances to this table and use this information for the preliminary evaluation of additional substances. 

By means of analogous approach as in the case of relationships in Fig. 1 we have studied mutual relationships between the characteristics of detonation and NMR chemical shifts of nitramines [26]. In contrast to the above-mentioned Fig. 1, the characteristics (i.e. heat of explosion or square of detonation velocity, D ) correlate with the N NMR chemical shifts, of nitro-group nitrogen atoms. Corresponding relationships for square of detonation velocity, D, are presented in Fig. 6. Here the if values correlate with the Sn values of the most reactive nitro groups [26]. Therefrom it follows that, that the primary fission of nitramine molecule is the same as that in the case of initiation by impact (see Scheme 1). Again this fact perfectly agrees with the conclusions drawn by Kohno et al. [27] fi-om the molecular dynamics study of impact and shock reactivity of nitramines. 

The physical, chemical and hazardous properties of a number of highly toxic or flammable substances that were in the past or being currently used in the warfare have been discussed in detail in several chapters in this book. Some of these compounds are further discussed under specific chapters, such as. Sulfur Mustards, Nerve Gases, Dioxin and Related Compounds and Napalm. These and many other compounds are in most cases grouped together in this book based on their chemical structures along with their toxic or flammable properties. Presented below is a brief discussion on various types of chemicals weapons developed for military applications. Explosive substances have been omitted from this section. They are discussed separately in this book under topics such as Explosive Characteristics of Chemical Substances, Nitro Explosives, Oxidizers and Organic Peroxides and also under specific title compounds in various chapters.
