• Analysis of the free energy of transfer from gas pltase to water laas been naade onforty orgauaic molecules carryixag the saune atounic group as natux'al anaino acids,xvhere tlaeir conforntatioua distribution and tlae effecxt of i?atramo1ecuIar interactioxtsare explicitly considered. The best model is presented for classify'ing all tlte co?asti-tuent atoxns into laydration-thermodynaxnically differeuat groups. Tlae atomic hydra-tuon parameter, i,e. tFte transfer free euaergy ])Cl' uuait accessible surface area, is defer-mined for each group. The intriuasic hydratioua energies of sulfur, OX)'gC11 and uaitrogexaatoms are estimated. Applicability to polar atoms o[' tlve assumption tltat the hydu-a-tion free energy of a molecule can be given by a linear contbination of accessible sur-face areas of tl?e constituent atoms, is exaxnitaed. TIIC transfer free energy' of an aminoacid is SIIOWII to be significantly affected by tlte sjcatial interference betw'een its maiuachain and side claain atoms.
