the probability of the presence and absence of substructures that may be associated with a compound that produced the searched mass spectrum along with additional predictions about this compound’s molecular weight and estimate of the numbers of atoms of chlorine and/or bromine that may be contained...
In such models masses are always lumped at molecule locations, and atoms vibrate as harmonic oscillators in the potential well of the force fields of their neighbors. Dispersion curves govern energy transmission. In a linear atomic chain, the dimensionless wavenumber range \(\,\kappa \in [-\pi...
Electron capture is most favorable for molecules that have hetero-atoms. For example: nitrogen, oxygen, phosphorus, sulfur, silicon, and especially the halogens: fluorine, chlorine, bromine, and iodine. The presence of oxygen, water, or almost any other contaminant interferes with the electron-...
In crystalline solids, electrons sense the environment and interact with (i) the lattice atoms, (ii) other electrons moving around the lattice, and (iii) with vibrations of the lattice. As a consequence of all these interactions, electrons move as if their mass was different from m0. This ...
Small-size metabolites display a greater structural variability in the arrangements of atoms and subgroups (only based upon atom valence properties) resulting in one elemental composition (EC) in a large number of possible isomers. Additional complexity in metabolome analysis in terms of structural ...
Hi. I read that the mass of nucleons in nucleus of Oxygen-16 (or nucleus of another atom) is less than the sum of its nucleons if they were separated (also the mass of 8 protons and 8 neutrons). But why does nucleons have less energy in nucleus of atoms than if they were separa...

Is there anywhere, any other combination of atoms that I could put these aldehydes on? On the straight chain, no. And on the branch chain, no. So actually these are kind of our only options right now. There's nothing else we can do. Now it turns out we have to remember, ...

Sophorolipids (SLP)—these are glycolipids composed of fatty acids of 16 or 18 carbon atoms bound to a sophorose as a hydrophilic part, produced by several species of Candida or other related yeast species. These glycolipids are used in detergents, lipsticks, lip creams, and eyeshadow [58]. ...
