Fig. 3.19 Identification of target modes. The azide bend at each -point normal mode is highlighted
the exception of HN 3 ), the covalent (more sensitive) compounds exhibit additional
δθ NNN at lower frequency. Within the framework of the up-pumping model of impact
initiation, this may be indicative of their higher sensitivity and offer a design target
for novel materials.
The position of max is important as the anharmonicity of ω < < max leads to
a rapid equilibration of the population of these modes in accordance with both upand down-conversion processes of Eq. 3.3 [6]. Experimental work has suggested that
