Solvent affinity theory
WebRf values do not have units since it is a ration of distances. Because mixture solvents are often applied Rf values are usually written as the following examples: Rf = 0.66 (60% Ethanol) - if % is given it is assumed that the mixture is in water hence 60% ethanol 40% water. Rf = 0.78 (Ethanol-Methanol mixture {1:2}) - a mixture of 1 part ...

WebThe non-covalent interactions between the host and the guest are determined using the quantum theory of atoms in molecules. Energy decomposition analysis indicates that the solvent phase influences the binding energy to a greater extent compared to the ... These analysis results reveal that ligand has low binding affinity on DNA and BSA ... WebThe TLC with the solvent hexanes and the reference benzophenone displays a strong affinity with the stationary phase as it has a very small Rf value. In the co-spot lane of the same TLC, the separation of compounds is displayed as one spot matches the reference and the other matches the sample.
