| Research Abstract |
We performed time-resolved Raman spectroscopy to investigate initiation dynamics of pentaerythritol tetranitrate(PETN) single crystal compressed by laser-driven shock wave. Shock induced frequency shift of the peaks showed the different behavior depending on each vibrational mode. It was found that there was a possibility that the vibrations related with NO_2 group had effect on shock-induced initiation.
