Therefore, experimental EELS vibrational data are needed to test proposed ideas and to validate theoretical models. Here we measure surface modes and acoustic and optical bulk modes in single MgO ...

"We mounted the whole thing on a vibration-isolating ... field—leading to a strong optical spring—that we use to produce the programmable defect mode. Credit: Clark et al Image of the apparatus.

A nanoscale spectroscopy technique reveals the orientation of surface-bound molecules with sub-nanometer precision by ...

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, ...

Near-infrared OFCs are conveniently produced by mode-locked femtosecond lasers ... The acetylene molecules are first pumped to an antisymmetric vibrational state using an in-house built ...
