Abstract
Scanning tunneling microscopy-freeze-fracture replication has provided a quantitative, high resolution description of the wave form and ampl itude of rippled bilayers in the P-beta' phase of dimyristoylphosphati dylcholine. The ripples are uniaxial and asymmetric, with a temperatur e dependent amplitude of 2.4 nm near the chain melting temperature dec reasing to zero at the chain crystallization temperature. The waveleng th of 11 nm does not change with temperature. The observed ripple shap e and the temperature induced structural changes are not predicted by any current theory.
