3 Vibrational Up-Pumping: Predicting Impact Sensitivity of Some …
Fig. 3.21 Two phonon density of states (2PDOS; (2) ) for the azides, calculated by enforcing both
ω q j and ω q j < 2 max (black). The difference between this restricted 2PDOS and that produced
by considering all combination modes is also shown (blue). The PDOS is given in red. max is
given as a vertical dotted line, and ω T is indicated with an arrow
