The final result is an additional increase of the surface potential, which has a similar magnitude as that obtained taking only steric effects
into account [21-26].

and the structure of monosubstituted benzene rings: an ab initio MO study," Journal of Physical Chemistry A, vol.
This is expected considering the fact that the energy changes are predominantly due to the torques on the conjugated bonds, as neither intramolecular attractions nor steric effects
are present to hinder the rotation of the nitro groups.
The reason for this is probably due to a subtle change in the conformation that is caused by one or more of the following: the shorter length of the amide bond compared to the disulfide bond, change in the electronic nature of the cystine mimic, and steric effects
. Unfortunately, insufficient material was obtained to perform structural studies using CD or NMR spectroscopy [38, 39].
This result suggests that HDMA significantly suppressed D908 dye adsorption by its bulky steric effects
. As a result of decreased dye adsorption, the value of [J.sub.sc] decreased from 16.4 to 14.8mA/[cm.sup.2], and the value of conversion efficiency also decreased from 6.9% to 6.6%.
This changed the adsorption properties of the carbons and caused steric effects
on the deposition of metals.
The geometrical preference of tetrakis(trialkylsilyl)dimetallenes found experimentally suggest that the geometry is very flexible and the major factor determining the preference is the steric effects
. In the next section, electronic models for the distortion around E=E bond and important factors controlling the geometrical preference are discussed more in detail.
This influence of the halogen atoms may be caused by electronic (induction, resonance) effects, steric effects
, or both.
(4) Several authors have sought to correlate the resistance of a polymer emulsion to hydrolysis by aqueous sodium hydroxide with resistance of a pigmented air-dried film to efflorescence (lime burn) and have concluded that resistance to hydrolysis is dependent on steric effects
of the polymer.
It can be presumed that, due to the presence of methyl groups inside the granules, the enzyme-substrate interaction is hindered by steric effects
Using the methods described by Guo and Karplus, a series of diene models were used to analyze the steric effects
that contribute to the torsion potential curve of 9-cis-UAB30.
The last two entries in Table 2 deserve attention because of the steric effects
. Replacement of the n-butyl group by isopropyl in the Grignard reagent increases the equilibrium constant by a factor of two in accordance of increasing hindrance to coordination with the donor.
