Oppositely Charged Ions at Water–Air and Water–Oil Interfaces: Contrasting the Molecular Picture with Thermodynamics

The surface-active ions tetraphenylarsonium (Ph4As+) and tetraphenylboron (Ph4B–) have a similar structure but opposite charge. At the solution–air interface, the two ions affect the surface tension in an identical manner, yet sum-frequency generation (SFG) spectra reveal an enhanced surface propens...
