Molecular dynamics computer simulations are used to study vibrational energy relaxation at liquid/vapor and liquid/liquid interfaces in order to gain insight into the microscopic structure of the interface region. We show that the microscopic local friction, which is responsible for the relaxation, is dependent both on the local density at the interface and changes to the local structure due to strong solute-solvent(s) interactions.
