In an effort to understand the details of shock compression of molecules used in energetic materials, we have conducted femtosecond laser experiments where a monolayer of energetic material simulants such as nitrobenzenethiol are subjected to a laser-driven shock wave while vibrational spectroscopy is used to probe their response. A monolayer is needed to attain the high time and space resolution necessary to make a detailed comparison to simulations. In support of the shock compression measurements, we also studied the response to flash heating and static high pressure up to 10 GPa.
