Measurement of Monomolecular Layers Using Specialized FTIR Grazing Angle Accessories
The analysis of monomolecular layers has traditionally been a challenging spectroscopic measurement due to the relatively low signal obtained from the sample. Specular reflectance at high “grazing” angles (around 80 degrees from normal to the surface) has been recognized as one of the best spectroscopic techniques to monitor monomolecular layers on reflective surfaces due to the enhancement of ...

متن کاملChain fusion and orientational ordering in monomolecular layers of amphiphilic molecules
A model which describes the competition between chain melting and orientational ordering in a monomolecular layer of long-chain amphiphilic molecules is studied. This model is analogous to the Berker-Cardy-Nelson-Scalapino model for phase transitions in films of 'HeHe mixtures. Their Midgal-Kadanoff renormalization-group approach is applied to the present problem. It reveals two phase transitio...
متن کاملX-ray Diffraction Techniques to Characterize Liquid Surfaces and Monomolecular Layers at Gas-Liquid Interfaces
X-ray and neutron scattering techniques are probably the most effective tools to be employed in order to determine the structure of liquid interfaces on molecular length scales. These are not different in principle from conventional X-ray diffraction techniques that are usually applied to three dimensional crystals, liquids, solid surfaces etc. However, special diffractometers that enable scatt...
متن کاملMixed monomolecular films of chlorophyll and cytochromes.
Mixed monomolecular films of cytochrome (Cyt) and chlorophyll (Chl) were spread at a nitrogen-water interface. A large interaction is observed between reduced Cyt f and Chl a in a mixed film. Oxidized Cyt f and Chl a in a mixed film show little evidence for interaction. Mixed monomolecular films of Chl a with either reduced or oxidized Cyt c appears to result in denaturation of the protein at t...
