Collapse<br />

Langmuir films<br />

G: gas phase<br />

L1: liquid expanded phase<br />

(e.g. saturated unbranched<br />

carbon chains: a 0 ≈30-50Å 2 )<br />

L2: liquid condensed phase<br />

(stronger molecular interactions,<br />

lower compressibilty<br />

S: solid (e.g. alcohols, esters:<br />

a 0 ≈19 Å 2 )<br />

G->L1: typical gas liquid transiton<br />

like in 3D<br />

L1->L2: transition not finally explained.
