steric

Scientifically , two main stabilization mechanisms can be distinguished: electrostatic and steric stabilization .

The difference of the relative position of H atom can affect the kind of bond-bond steric exchange energy.

In a tetrahedral configuration, the substituted groups sre located in two perpendicular planes, the steric effect is much weaker.

It can be concluded that the activity of these inhibitors was mainly dependent on the steric, electrostatic and hydrogen bond acceptor.

Some albumin molecules may have undergone steric modification or ligand binding such that the immunoreactive sites have become obscured.

It follow therefore that the steric blocking effects of substituents are reflected in adverse kinetic, rather than thermodynamic factors.

hydration layer on the particle surfaces by steric interference, which leads to the enhancement of the stability for Cu suspensions.

The results indicate that the larger steric hindrance in the amino alcohol unit of Schiff base ligands leads to higher enantioselectivity.

It is investigated that both steric and electric hindrance are of great importance for the stable dispersion of GNP in water.

NMR relaxation times of four protons at different positions versus steric effect and mixing proportion in ligand mixtures were monitored.

The results indicated that steric, electrostatic and hydrogen-bond donor fields were main factors to inhibition performance.

The stereoselectivity was improved by increasing steric hindrance of the reactions.

Thus, we concluded that the steric hindrance of C-terminus might play an important role in opioid receptor affinity.

Steric effects in 126 may also be responsible for its inertness to the Grignard reagent.

Macromolecules cannot approach the ligand owing to steric hindrance of the matrix .

Some influences of steric effect, reaction temperature and solvent effects were discussed.

A rather more complex case is that of steric isomerism.

The steric- cally hindered amines are non-aggressive towards fluoroelastomer O-rings or seals.

Severe steric effects at the reactive carbon would impede the substitution.

The second Noahic covenant (Genesis 9: 8-17) was a universal non-steric covenant promising the restraint of judgment until the last day.

However, the steric effects related to the substituents of PS and EVA cancels this catalytic behaviour.

the steric effect of the organic gel.

In the forth chapter, we solved the problem of steric hindrance in the third chapter.

Because of the steric hindrance, the isopropylated 2-MN can gain higher 2, 6-selectivity than the methylated one.
