Abstract

The study of (buried) interfacial monolayers has greatly benefitted from the development of the interface specific nonlinear optical techniques known as IR-visible sum-frequency generation. In particular the ability to probe individual vibrational resonances of the constituent molecules of the monolayer has proven to be extremely valuable. For such studies one often uses a tunable IR source whose bandwidth is narrow compared to the width of the vibrational bands.
