Recent advances in multidimensional nuclear magnetic resonance methodology to obtain 1H, 15N and 13C resonance assignments, interproton distance and torsion angle restraints, and restraints that characterize long-range order, coupled with new methods of structure refinement and novel methods for reducing linewidths, have permitted three-dimensional solution structures of single chain proteins i...
Resonant photon tunneling was investigated experimentally in multilayer structures containing a high-contrast (TiO(2)/SiO(2)) Bragg mirror capped with a semitransparent gold film. Transmission via a fundamental cavity resonance was compared with transmission via the Tamm plasmon polariton resonance that appears at the interface between a metal film and a one-dimensional photonic bandgap structu...
the concept of resonance assisted hydrogen bond (rahb), which usually occurs in b diketons, has a remarkable role in chemistry. these molecules, which contain heteroatom particularly o and n, are species with biological interest in protein folding and dna pairing. therefore, the amplification of hydrogen bonds strength by substituents may be important in life sciences. in the current research, ...
We have observed kilohertz and sub-kilohertz resonance structures in RF-optical double resonance experiments of rare-earth-doped solids, when the frequency of the RF ® eld is scanned across the hyper® ne transitions while monitoring the resonant optical absorption of a CW laser. The eå ect is observed only when the laser spectral width is broad compared to the hyper® ne structure. The observed ...
