We have observed the pure rotational spectra of HBr isotopomers in their v = 0 and v = 1 states between 0.97 and 1.02 THz. i. e. the HBr .7 = 2—1 and the DBr .7 = 4 — 3 transitions, respectively. In the analysis, all presently available rotational transitions of all isotopomers have been fitted to a Dunham-type Hamiltonian to obtain the isotopically invariant parameters, including vibrational a...

Staphylococcus aureus FemA mutant grown in the presence of an alanine-racemase inhibitor was labeled with d-[1-(13)C]alanine, l-[3-(13)C]alanine, [2-(13)C]glycine, and l-[5-(19)F]lysine to characterize some details of the peptidoglycan tertiary structure. Rotational-echo double-resonance (REDOR) NMR of isolated cell walls was used to measure internuclear distances between (13)C-labeled alanines...

The posterior parietal cortex (PPC) contains viewer-centered spatial maps important for reaching movements. It is known that spatial reaching deficits emerge when this region is damaged, yet less is known about temporal deficits that may also emerge because of a failure in sensory-spatial transformations. This work introduces a new geometric measure to quantify multimodal sensory transformation...
