摘要：

Adsorption layers of n-dodecanol at the water/air interface show phase transitions at low temperatures [Vollhardt, Famerman, Emrich, J. Phys. Chem. B 104 (2000) 8536]. Using a drop shape technique it is shown that the dilational elasticity disappears in the coexistence region of the adsorption layer. The relaxation time between the condensed and liquid-like surface states is in the sub-second time range. (C) 2003 Elsevier Inc. All rights reserved.
