to change the space group. Olex2 will try to remove the symmetry related atoms, however if the atoms do not overlap within some value, they have to be removed manually or by typing: >>fuse r command, where r is the radius within which atoms of the same type get merged into a single...
我的意见是，该化合物应该是消旋体，当然我不是学有机的，应该从你的合成过程综合考虑 ...
第一，你这化合物没有原子数超过P的，因此钼靶确定其绝对构型是不准确的，第二，P-1是中心对称空间群...

The MAXXI Museum in Rome has announced the five young designers who will compete for the opportunity to design and build a space for live summer events in the large courtyard of the MoMA PS1 in NY, the MAXXI Plaza in Rome, and - for the first time - at Turkey's Istanbul Modern. Each...

If d ≥ 3 and p ≥ (d + 2)/(d − 2), then the problem in the entire space has no nontrivial solution. For the first time, this problem was studied by a variant of the variational method. However, it is known to the specialists in the field that it is also interesting to ...
The space group of the complex crystals was found to be I222 with cell parameters a = 63.4 Å, b = 96.8 Å, and c = 187.3 Å. Native diffraction data were collected at beamline X4A at the National Synchrotron Light Source (NSLS) at Brookhaven National Laboratory using a wavelength ...
On the orbits of the hat-function and on countable maximal commutative semigroups of continuous mappings of the unit interval into itself For suitable bounded operator semigroups (e tA ) t≥0 in a Banach space, we characterize the estimate ‖Ae tA ‖≤c/F(t) for large t, where F is...
Cy (2)). This has been confirmed by single-crystal X-ray diffraction studies for 2 with the following crystal data: tetragonal space group P421c, a = 12.774(2) , c = 9.934(2) , Z = 2. The molecule possesses an eclipsed structure with strong N-HCl intramolecular hydrogen bonding, ...
