Spacecraft Position and Attitude Formation Control using Line-of-Sight Observations [PDF]

, 2014
This paper studies formation control of an arbitrary number of spacecraft based on a serial network structure. The leader controls its absolute position and absolute attitude with respect to an inertial frame, and the followers control its relative ...

Enantiomeric Mixtures in Natural Product Chemistry: Separation and Absolute Configuration Assignment

Molecules, 2018
Chiral natural product molecules are generally assumed to be biosynthesized in an enantiomerically pure or enriched fashion. Nevertheless, a significant amount of racemates or enantiomerically enriched mixtures has been reported from natural sources ...

Foundations of Relational Particle Dynamics

, 2009
Relational particle dynamics include the dynamics of pure shape and cases in which absolute scale or absolute rotation are additionally meaningful. These are interesting as regards the absolute versus relative motion debate as well as discussion of ...

Monte Carlo configuration interaction applied to multipole moments, ionisation energies and electron affinities [PDF]

, 2013
The method of Monte Carlo configuration interaction (MCCI) [1,2] is applied to the calculation of multipole moments. We look at the ground and excited state dipole moments in carbon monoxide.

Two-dimensional Noncommutative Gravitational Quantum Well

, 2017
In this paper we consider two kinds of noncommutative space-time commutation relations in two-dimensional configuration space and feature the absolute value of the minimal length from the generalized uncertainty relations associated to the particular ...

Automatic assignment of absolute configuration from 1D NMR data [PDF]

, 2005
Opposite enantiomers exhibit different NMR properties in the presence of an external common chiral element, and a chiral molecule exhibits different NMR properties in the presence of external enantiomeric chiral elements.

The Absolute Configuration of Dibromopalau'amine

European Journal of Organic Chemistry, 2010
AbstractWe determined the ensemble of conformations and therelative configuration of dibromopalau'amine by using NMR parameters such as 3J couplings, ROEs and residual dipolar couplings. Based on the ensemble electronic circular dichroism (ECD) and optical rotatory dispersion (ORD) spectra were calculated using DFT and compared to experiment.
