Abstract

Herein, it is shown that aromatic spreading solvents can be detected using in situ UV spectroscopy at the air-water interface beyond the common accepted time for evaporation of 10-20 min in the preparation of a Langmuir monolayer. Toluene and benzene, even though not significantly surface active, can be detected, and their behavior as a function of time and temperature is investigated. To our knowledge, this is the first time that the vibrational fine structure of the benzenoid bands are detected at the air-water interface.
