We studied the motion of the small water molecules and some organic molecules of different shape and polarity (benzene, cyclohexane, 1,4-dioxane, n-pentane, neopentane and n-dodecane) in MCM-41 of pore diameters between 2.8 and 6.5 nm. View chapter Book series 1998, Studies in Surface Scie...
The effect of water on the molecular motion of alginic acid (Alg) was investigated by differential scanning calorimetry. Alg is a copolysaccharide consisting of guluronic (G) and mannuronic acid (M). A phase diagram of water-Alg with various M/G ratios, such as 1.20, 0.88 and 0.18, was...

The NIR absorption band of OTTTB can be assigned to the efficient ICT effect of strong D‒A interaction46,47. To investigate the intramolecular motion in aggregate states, water was gradually added into the THF solution, and the PL spectra were recorded (Fig. 2b, c). The PL intensity ...

In analytical analysis, the removal of solvents may greatly accelerates the speed of analysis. This option is achieved through -C or -P. The -C option allows the direct use of ASL expressions to remove a portion of the system, while -P evaporates the water in the solvent box, retaining ...
of gas transport 1°-14. There the investigations of the diffusion of a penetrant molecule through amorphous polymers clearly show two types of motion 1°'13'14-. For relatively long periods of time (typically a few lOOps) the gas molecules stay in certain small regions of space. Duri...
negligible (in contrast to a continuum description), the response of the molecular water system might still be similar to the continuum description if the time and ensemble averages satisfy the ergodic hypothesis and the scale of the average is enough to recover the classical thermodynamic ...
the intermolecular H-bond between FHC and the solvent molecules and proton trajectories, we found that ESIPT occured in acetonitrile and alcohols as a combination of low frequency high amplitude donor-acceptor bending motion and charge redistribution in the excited state, that were modulated by the ...
the enhancement in phosphorescence after the thermal annealing process is attributable to the ordered molecular arrangement via molecular motion. The multiple peaks in the wide-angle range, especially the increases in the intensity of the diffraction peak at 2θ = 23° in the XRD spectrum ...
