Q. Give one example of :Triatomic molecule Q. By giving examples, define the term triatomic molecules. Q. Give one example each of homoatomic triatomic molecule and hetroatomictetra-atomic molecule. Q. Give examples for diatomic and triatomic molecules? Q. Give one example of molecule a tr...
The two cases, free base phthalocyanine and rare gas-iodine van der Waals molecules, would appear to be about as unrelated as it is possible to get given the finite size of the periodic table, and yet the phenomena that we observe in these two systems can be described using very similar ...
Both molecules are achiral due to a plane of symmetry along carbon 1 and 4. The "r" and "s" are not capitalized because the tert-butyl group can freely rotate, making the compound the same regardless of the position of the hydroxy or methyl group on the wedge/dashes. This can be ...
A way to stable, highly emissive fluorubine dyes: tuning the electronic properties of azaderivatives of pentacene by introducing substituted pyrazines Pentacene and its derivatives are among the most important examples of 蟺-electron-rich molecules used in organic field effect transistors. The replacemen...
The entropy of very long flexible molecules in the presence of topological constraints is studied, and a formula deduced which needs the probability that a random walk will have a particular topological specification. Examples are solved... Edwards,S F - 《Proceedings of the Physical Society》 被...
The flux (turnover) per molecule is expanded in powers of the enzyme concentration (a "viral" expansion). Aggregation of the enzyme molecules in solution is considered as a special case. In the second example, we treat an arbitrary lattice of enzyme molecules, with nearest-neighbor interactions...
KJ Kim,HL Lee - 《Molecules & Cells》 被引量: 239发表: 2005年 Multiple diploid hybrid speciation of the Canary Island endemic Argyranthemum sundingii (Asteraceae) There are several well-documented examples of multiple hybrid origins of polyploid species. Herein we report the first, to our knowle...
examples of these fittings at different incident angles. The spectral positions of the fitted resonances were then extracted and plotted as a function of angles (blue dots in Fig.1d). The complicated dispersive behaviours of these resonances were then fitted using a (4 × 4) matrix of ...
Calcium stabilizes a pre-catalytic configuration of the active site As described above, the crystal structure shows the presence of a Ca2+ ion near the −1 subsite. The Ca2+ ion is coordinated by the His288 Nε2 atom and by six water molecules in a pentagonal bipyramidal coordination geomet...
The X-Ray Crystal Structures of p-Sulfonatothiacalix[6] arene Inclusion Complexes with Lanthanide Metal Ions (M=Gd, Ho and Er) and Water Molecules Crystals of Co 2 ( X 2 O 7 )·2H 2 O, X =P/As were synthesized under hydrothermal conditions. Their crystal structures were determined by...
