The importance of water molecules for the structural dynamics and the functioning of ribozymes was investigated by Rhodes and co-workers. They studied non-coded RNA using a combination of explicit solvent molecular dynamics and single molecule fluorescence spectroscopy approaches (Rhodes et al 2006).

Solubility refers to the extent to which a substance will dissolve in a solvent. Molecular substances that do dissolve in water may or may not ionize into ions. If they do ionize, they may or may not ionize completely. 

Before the raw data can be fitted to a thermodynamic model it must first be converted into mass or mole fractions. This operation can be accomplished quickly using a Microsoft Excel spreadsheet that is linked to the Aspen. aprbkp file in order to obtain the solvent molecular weights and temperature dependent densities. The molar volume of Form A Cimetidine is also required for this conversion, however, as is often the case it was not available so a density of 1 g/ml has been assumed. 

The most common weak specific interaction is hydrogen bonding. More often than not hydrogen bonding is invoked by various investigators on the basis of analogy, chemical intuition, knowledge of solvent molecular structure, or because the data do not correlate well with other models. In a few cases sub-...

The interpretation of conductance data is complicated by the labile nature of the lanthanide complexes in solution which results in ligand exchange and dissociation reactions. It is difficult to understand the nature of the complex species present in solution. A combination of conductance data and molecular weight determination may be useful in determining the coordination number and structure of the complexes in solution. However, due to the poor solubility of lanthanide complexes in suitable solvents, molecular weight data have been obtained for only a few complexes. The dissociative reactions of lanthanide complexes in solution are well illustrated by the TPPO complexes of lanthanide isothiocyanates (202). In chloroform solution, the dissociation...

B. Saturated Hydrocarbons. Purging and freeze-pump-thaw methods are effective in degassing paraffins. Distillation with the elimination of the first fractions produces dry solvent. Molecular sieves may also be used to remove water. Distillation from sodium-benzophenone ketyl is highly effective in obtaining very low levels of water and oxygen. Commercial grades of hydrocarbons are often contaminated with olefins, which can be eliminated by several washings...
