Energetics of adsorption of neutral and charged molecules at the air/water interface by second harmonic generation: Hydrophobic and solvation effects
A Castro, K Bhattacharyya, KB Eisenthal - The Journal of chemical …, 1991 - pubs.aip.org
Surface second hannonic generation has been used to study the adsorption of alkyl phenols
and anilines and their respective ions to the air/water interface. The free energies of
adsorption of the neutral molecules were obtained using a simple Langmuir model. The
quantitative effects of the opposing hydrophobic and solvations forces on molecular
adsorption were investigated by varying the chain length of alkyl phenolate and
alkylaniIinium ions. An alkyl chain of at least five carbons was found to be necessary to …
