Abstract
The evaluation of critical exponent beta for two-dimensional condensat ion of organic adsorbates at the mercury-aqueous solution interface is carried out using spin-1/2 generalized Ising model formalism. The est imated value is in agreement with Onsager's value of 0.125 pertaining to two-dimensional Ising model with nearest neighbour interaction ener gies. (C) 1997 Elsevier Science B.V.
