Proton Spin Relaxation Study of Molecular Motions in the Lyotropic Liquid Crystalline System Potassium-Laurate Water
T h e p a p e r presents and discusses m e a s u r e m e n t s of the p r o t o n spin Tx r e l axa t ion d i spe r s ion over a b r o a d f r equency range (100 H z 3 0 0 M H z ) in the mice l la r , hexagona l , cub i c and l amel la r p h a s e s of lyotropic po t a s s iumlau ra t e wa te r mixtures . T h e results clearly show that in the an i so t rop ic phases (hexagonal , l amel la r ) ...
متن کاملStructure and Molecular Motions in Rubidium Tetraphenylborate
By X-ray diffraction it was found that at 293 K the crystals of rubidium tetraphenylborate are tetragonal, space group I4̄2m, a = b = 11.212(2) Å, c = 8.098(2) Å, with 2 molecules of Rb[C24H20B] # in the unit cell. The molecular reorientations as functions of temperature were studied by H NMR. Two types of motions were detected: an anisotropic reorientation of the tetraphenylborate anions about ...
متن کاملMolecular Motions in Functional Self-Assembled Nanostructures
The construction of "smart" materials able to perform specific functions at the molecular scale through the application of various stimuli is highly attractive but still challenging. The most recent applications indicate that the outstanding flexibility of self-assembled architectures can be employed as a powerful tool for the development of innovative molecular devices, functional surfaces an...
متن کاملInvestigations of Random Molecular Motions by NMR
The aim of this contribution is to demonstrate that NMR spin relaxation is an efficient method for the investigation of random molecular motions. Information on random motion is important for the characterization of liquids, polymers, and biological samples. Random motions are time-dependent phenomena and have to be treated with timedependent statistical mechanics. On the other hand, spin relax...
متن کاملDSMM: a Database of Simulated Molecular Motions
We describe a Database of Simulated Molecular Motions (DSMM). This database is designed to serve as a single searchable site for locating movies and animations from simulations of biomolecules. DSMM is accessible via a webserver at: http://projects.villa-bosch.de/mcm/database/dsmm.
