Special techniques of high resolution electron microscopy applied to liquid crystalline polymers in the smectic and discotic phases revealed characteristic distortions from the perfect lattice periodicity as well as defects. In order to verify the direct relationship between electron microscope images and structure, computer simulations were performed. Agreement was found between simulated image and structure proposed on the basis of evidence from electron diffraction imaging. A theory was developed to explain this unexpectedly good agreement. Image restoration by frequency filtering in reciprocal space was found to give good results for the discotic material
Neben den1 Chlor‐1‐fluorid besteht auch ein Chlor‐3‐fluorid, welches durch Erhitzen von CI2 oder CIF mit überschüssigem F2 dar‐ gestellt wird. Die umkehrbare Reaktion CIF + F2 ⇆ CIF3 führt zu einem Gleichgewicht, in dem bei 250° Zahl der CIF‐Moleküle ein Mehrfaches der CIF3‐Moleküle ist. Die Zusammensetzung des neuen Fluorids is durch Analysen und Dichtebestimmungen sichergestellt. Seine physikalischen und chemischen Eigenschaften werden mit ‐ geteilt.
Besonders bemerkenswert ist die Lebhaftigkeit und die Mannigfaltigkeit der Reaktionen des CIF3.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
