Sentence examples for by substituent from inspiring English sources

That is, the supporting compounds of this BAS are those obtained by substituent modifications from the BAS.

Although molecular mechanism of action is unknown, toxicity is more affected by substituent group on cadinene skeleton, and less affected by degree of unsaturation.

It was found that control of the stereochemical preference between (S∗,S∗) and (S∗,R∗) diastereomers by substituent modification of the ligand sidearms was possible in the process of crystallization with the preferred coordination of the sidearms generally consistent with expectations based on the electron-donating or -withdrawing properties of the sidearm substituent groups.

The adsorbability of a wide series of aromatic derivatives (38) on mercury from aqueous solution at constant potential (Epzc or close to it) cannot be simply accounted for by the "aromaticity" of the compounds, at any rate modulated by substituent groups on the aromatic moiety, even if the adsorbates show a common planar disposition on the surface in the adsorbed state.

High resolution 13C CP/MAS solid-state NMR analyses indicate that the spin-lattice relaxation time (T1ρH) in all PBPMA blends are homogeneous on the scale at which spin-diffusion occurs within the time T1ρH, also due to the enhancement by substituent inductive delocalization.

The relative stability of the phenanthridinium cations is governed by substituent effects, which act opposite to the situation in electron-rich TS: acceptor substituents destabilise the cation (IIIb, c, d, f), whereas donor substituents stabilise it (IIIe).

In addition to the very common fatty acids with straight saturated or unsaturated acyl chains, many fatty acids are chemically modified by substituents on the hydrocarbon chain.

Each symbol corresponds to a ligand, and shape and color are determined by substituents.

When such position is blocked by substituents the 3-aza-Cope rearrangement occurs at room temperature.

The effect on the luminescent property by substituents in the heterocycle and phenyl rings, have been studied as well.

However when base-catalysed decomposition is prevented by substituents, products arising from a room temperature aza-Cope rearrangement are isolated.
