Direct enantiomeric discrimination through antisymmetric hyperfine coupling

Hyperfine Coupling Constants

The IH hyperfine coupling constants of free radicals and ions have been successfully studied by our newly modified s-p· separation type INDO-MO method->, and the most of our calculated coupling constants are significantly better than the corresponding results of the conventional INDO-MO method."" The nuclear hyperfine coupling constant is assumed to be directly proportional to the 2s spin densi...

Microwave chirality discrimination in enantiomeric liquids

Real-time weed/crop discrimination through fast direct image registration

This paper presents a computer vision system that is able to discriminate between weed patches and crop rows in real-time, from videos taken directly from a tractor moving through the field. Weed/crop discrimination is highly simplified thanks to video stabilization. We present a simple but effective variant of the inverse compositional algorithm for image alignment, and show that on our videos...

Theoretical calculations of hyperfine coupling constants for muoniated butyl radicals.

The hyperfine coupling constants (HFCCs) of all the butyl radicals that can be produced by muonium (Mu) addition to butene isomers (1- and 2-butene and isobutene) have been calculated, to compare with the experimental results for the muon and proton HFFCs for these radicals reported in paper II (Fleming, D. G.; et al. J. Phys. Chem. A 2011, 10.1021/jp109676b) that follows. The equilibrium geome...

Nuclear Quadrupole Hyperfine Structure of the Direct /-Type Transitions

The direct Itype transitions of H l 3 C , 4 N l 6 0 in the vibrational states ( i^ i ' s ) = (01) and (03) were measured in the frequency range from 18 to 40 GHz. These transitions show a nuclear quadrupole hyperfine structure caused by the l 4 N nucleus, which could partially be resolved at Doppler-limited resolution. The analogous transitions of the parent species. H l 2 C l 4 N 1 6 0 , were ...
