An international research collaboration headed by VU-scientist Jeroen Koelemeij developed a new method to measure vibrational frequencies in the molecular hydrogen ion at four hundred times higher ...

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, ...

BLOOM (TAMPA) – After introducing the world of Vibrational Frequency Analysis on Bloom, husband-and-wife researchers Elena Bensonoff and Alejandro Ferradas returned for a powerful second segment — ...

Phonons are sound particles or quantized vibrations of atoms in solid materials. The Debye model, a theory introduced by physicist Peter Debye in 1912, describes the contribution of phonons to the ...

The vibrational motion of an atom in a crystal propagates to neighboring atoms, which leads to wavelike propagation of the vibrations throughout the crystal. The way in which these natural vibrations ...
