Double Quantum Two

چکیده
The rst double quantum two-dimensional Fourier transform electron spin resonance (2D-FT ESR) experiments are reported. Extension of 2D-FT ESR to enable detection of the M s =2 transition enhances the capability of ESR in studying structural properties, (i.e. distances in bilabeled molecules). A distance of 21 A was found for a poly-proline peptide, spin labeled at both ends, in agreement with earlier measurements using uorescence energy transfer.

متن کاملOPTIMUM SHAPE DESIGN OF DOUBLE-LAYER GRIDS BY QUANTUM BEHAVED PARTICLE SWARM OPTIMIZATION AND NEURAL NETWORKS
In this paper, a methodology is presented for optimum shape design of double-layer grids subject to gravity and earthquake loadings. The design variables are the number of divisions in two directions, the height between two layers and the cross-sectional areas of the structural elements. The objective function is the weight of the structure and the design constraints are some limitations on str...
متن کاملQuantum Interference Control of Ballistic Magneto- resistance in a Magnetic Nanowire Containing Two Atomic- Size Domain Walls
The magnetoresistance of a one-dimensional electron gas in a metallic ferromagnetic nanowire containing two atomic-size domain walls has been investigated in the presence of spin-orbit interaction. The magnetoresistance is calculated in the ballistic regime, within the Landauer-Büttiker formalism. It has been demonstrated that the conductance of a magnetic nanowire with double domain walls...
