The shape of the water molecules is fixed by assuming an OH distance of 0.987 A. Finally the plane in which a water molecule is lying is determined by minimizing the sum of the squares of the distances of the two protons to their respective acceptor atoms....
The electrophilic monomer can be aromatic in nature and can contain two or more, for example three, electrophilic groups per molecule. The second monomer can be a trimesoyl halide. For the case of acyl halide electrophilic monomers, acyl chlorides are generally more suitable than the ...
Finally, the carboxylic acid residues are directed away from the rest of the molecule to facilitate hydrogen bonding interactions. The most prominent intermolecular interactions in the crystal of (I) are hydroxyl-O—H⋯O(carbonyl) hydrogen bonds occurring about a centre of inversion, indicating ...
In this equation, ΔGs(A) and ΔGs(A-) are the solvation energies of molecule A and its anion A-, respectively, and ΔEg(A→A-) is the energy difference between molecule A and its anion (which is defined as the redox energy in the gas phase). Based on this thermodynamic cycle, ...
aadaptive growth of plants is regulated by small-molecule regulators called plant hormones . Plants regulate hor- mone response pathways at multiple levels including hormone biosynthesis, metabolism, perception, and signaling. In the case of auxin, elegant studies have shown that the regulation of aux...
