Corrosion mitigation in acidic conditions is most frequently achieved through the addition of organic species (corrosion inhibitors), which protect the metallic substrate by the formation of dynamic adsorbate layers. Understanding of this process, however, is rather limited, with nanoscale mechanistic detail being largely absent, and thus inhibitor selection is currently largely empirical process. Given this scenario, we are employing a novel technique, vibrational sum-frequency spectroscopy (or VSFS), in order to gain insight into such inhibited interfaces.
