As methods for fractionation and isolation of organic matter in freshwaters have evolved, and as the intensity of research has waxed and waned in various academic disciplines, a rich and potentially confusing n
Because the notion of mechanism has these two different senses, yet is thought of as depicting (in either sense) one and the same process, it serves as a conceptual bridge, linking the classical structural theory of organic chemistry with the more abstract models of transformations. When the ...
The carbon-carbon double bond won’t rotate and so you would have to take the models to pieces in order to convert one structure into the other one. That is a simple test for isomers. If you have to take a model to pieces to convert it into another one, then you’ve got isomers....
DOI: 10.1021/jo01294a030 This paper introduces the concepts of stereoselectivity in aldol reactions when an enolate is adding to another carbonyl compound. Transition-state models are discussed, and the role of Li ions in chelation is also illustrated.00...
these interactions with the rotations of the octahedra in the perovskite lattice, an attempt, which, as we shall discuss below, is misleading. A similar attempt was made by others to answer questions such as: Does the inorganic framework deform on its own and the MA cation then accommodates ...

ML along with different models of deep learning has found diverse applications in organic chemistry (Glielmo et al., 2021; Keith et al., 2021; Mater & Coote, 2019), such as (1) Structure and Transition States Optimization (Laghuvarapu et al., 2020), (2) HOMO-LUMO Gap and Bond ...
Next to prediction, data-driven models can also be used to determine the key solute–solvent–membrane properties influencing the separation process [6,10]. Moreover, these models are being used in combination with mechanistic models as so-called hybrid models to provide extra insights and to ...
