The properties of these materials are such that on heating from the solid to the isotropic liquid state, phase transitions occur with the formation of one or more intermediate anisotropic liquids. The unique and sometimes startling properties of these liquid crystals are the propert

Klaus Weltnerration and regard, Dr. Horst Seidel. It was my great good fortune to have him as a guest in my laboratory for a year. My students and I had the benefit of his deep and contagious love of physics, his superb physical insight, his clever approach to the design of experiments, his profound ability to s

Klaus Weltnerthose of isotropic liquids. In 1888, Reinitzer performed experiments with molten cholesteryl benzoate under a polarizing microscope and discovered two melting points. The substance melted from a solid at 145.5°C into a cloudy but completely fluid phase, and only at a much higher temperature (1

Klaus Weltnerat zero frequency are important in NMR relaxation. Both spin-lattice and spin-spin relaxation rates are generally governed by random motion of spin-bearing molecules. Typically, a molecule remains in one state of motion for a short time (10.–10. s). After this time, it suffers a collision with one o

A set of microscopic order parameters was introduced in Chapter 2 for rigid molecules in a uniaxial phase. They may be determined from the splitting or shift of spectral lines in NMR spectra
