Abstract

Ultrafast shock compression and heat shock experiments using molecular monolayers provide atomic-scale time and space resolution. Heat shock refers to flash-heating a metal substrate by 600-800 K causing heat to flow into different probed functionalities of adsorbed monolayer molecules. We have developed methods to greatly improve monolayer spectra using vibrational sum-frequency generation with nonresonant suppression. Monolayer engineering with atomic precision is used to study shock-molecule interactions in energetic material simulants. Monolayer vibrational spectra at high pressures are obtained using diamond-anvil cells with photonic substrates.
