Scientists observed charge separation in a solar cell dye, driven by nuclear vibrations, not solvent effects, reshaping views on light-induced transport. (Nanowerk News) Whether in solar cells or in ...

Anharmonic vibrational spectroscopy goes beyond the idealised harmonic oscillator model to characterise molecular vibrations with greater accuracy. By accounting for anharmonicity, researchers can ...

A nanoscale spectroscopy technique reveals the orientation of surface-bound molecules with sub-nanometer precision by confining light in a near-field region between a scanning probe and substrate.

The ultrafast placement of an electron in a polar liquid generates collective molecular vibrations in a spherical nano-volume. The vibrations change the diameter of this sphere periodically for more ...

Vibrational frequency analysis underpins the interpretation of molecular vibrations through computations that predict spectral signatures such as infrared and Raman bands. At its core lies normal-mode ...

According to a study published in Nature Communications, researchers have created an extremely sensitive detector for identifying molecules based on their infrared vibrational “fingerprint.” ...

Electrons can be ‘kicked across’ solar materials at almost the fastest speed nature allows, scientists have discovered – challenging long-held theories about how solar energy systems work. The finding ...

Getting a class of fluorescent synthetic dyes used for medical imaging to embed in the membranes of cancer cells and vibrate rapidly induces necrosis. With whole-molecule vibrations lasting for less ...

Whether in solar cells or in the human eye: whenever certain molecules absorb light, the electrons within them shift from their ground state into a higher energy, excited state. This results in the ...
