Compared with the optical rotation calculation step, the geometry optimization step is more influential. Computational parameters including hybrid functionals, basis sets and solvation models could exert a great effect on the Boltzmann distribution, leading to substantial variation in the SORs. To achieve...
The Monte Carlo movements included random translation and rotation of rigid bodies with a maximum of 10 Å and 1 radian, respectively. The sampling was run for 15000 frames with 32 replicas, with temperatures ranging from 1.0 to 2.5 (technical units). The 25% best scoring models were ...
The rotation was set at 0.4°/step for 180°. The exposure time was set at 3564 ms. Skyscan softwares were used for cross sectional reconstructions with NRecon, 3D reconstruction with CTAn and CTVol. Histology and histomorphometric analyses...

Organic Chemistry Stereochemistry Enantiomeric Excess (ee): Percentage of Enantiomers from Specific Rotation with Practice Problems In the previous post, we discussedracemic mixtureswhich consist of equal amounts of twoenantiomers. Racemic mixturesarenot chiralas they are notoptically active. For example,...
29 After 50 years old, non-OA women have greater external hip adduction and internal rotation along with increased hip extension moments compared to men, even after normalizing for body size and walking speeds. The walking style or kinematics seems to be the main determinant in the observed ...

The detailed landscape also suggests that, at and beyond r = ~1.3 nm, both SPD and NSPD start to exhibit similar preference in all orientations, i.e., polyamines experience full rotation degrees of freedom. This is indeed an entropically favorable process. At r = ~1.3 nm...
