and accounting for double or triple bonds by counting them multiple times. The final configuration is determined by tracing a path from the highest to lowest priority, with clockwise paths designated as R and counterclockwise as S. Adjustments are made if the lowest priority group is not in the...
This video showshow to quickly identify enantiomers, diastereomers and meso compounds in chiral molecules with more than one chiral center using R and S configuration and the swap method. Learn how to use an Organic Chemistry Model Kit to visualize the plane of symmetry in meso compounds. ...

Overall, the results indicate that the support layer configuration played a dominant role in influencing membrane total porosity rather than the fabrication method. For both DBE and SDC, membranes with a support layer had a larger dry volume (Vd) than the pristine membrane, as shown in Supplement...
To determine theabsolute configuration(R or S) ofchiralcenters in Fischer projections, identify the position of the lowest priority group (4). If group 4 is vertical, the configuration is as drawn; if horizontal, it is flipped. This method simplifies the process, especially for complex Fischer...

The reorganization energy is the energy required to force the reactants to have the same nuclear configuration as the products without permitting the electron transfer. If the entropy changes are ignored, the free energy becomes energy or potential energy [37–42]....
