Researchers developed a new method that allows, for the first time, to elucidate the chiral structure of molecules -- the exact spatial arrangement of the atoms -- by nuclear magnetic resonance (NMR) ...

Vibrational sum-frequency generation (VSFG) is a nonlinear spectroscopic method widely used to investigate the molecular structure and dynamics of surface systems. However, in far-field observations, ...

Generation of circularly polarized nonlinear signals from chiral metasurfaces with rotational symmetry under arbitrarily polarized excitation. Left and right circularly polarized light, where the ...

(a) Electric field of LCP and superchiral light. (b) (Left) Schematic illustrating the generation of superchiral fields by focusing twisted RP beams. (Right) Theoretical model used to calculate the ...

Researchers have analyzed the stepwise hydration of prolinol, a molecule widely used as a catalyst and as a building block in chemical synthesis. The study shows that just a few water molecules can ...
