Abstract

Femtosecond laser-driven shock compression experiments are described using nonlinear coherent vibrational sum-frequency generation spectroscopy (SFG) probing of molecular materials. SFG selectively monitors molecular groups at surfaces and interfaces, providing a high degree of spatial resolution. In initial experiments a self-assembled monolayer of long-chain alkane molecules is studied, where SFG sees only the methyl (-CH3) head groups. The plane of methyl groups is just 1.5Å thick. Shock-induced bending of the chain and shock-induced rotations around carbon-carbon bonds are observed. Possible future directions are discussed.
