Molecular dynamics in real time

A novel spectroscopic method allows ultrafast processes within molecules to be observed

08-May-2024 - A European research team has developed a novel spectroscopic method that can be used to observe ultrafast dynamic processes of electrons and vibrations within molecules – with atomic resolution and in real time. A team from the University of Jena supported the experimental team in Barcelona in ...

Artificial intelligence for better diagnostics

Standardized methods facilitate the evaluation of Raman spectra

15-Dec-2021 - Light-based methods are increasingly used for analytical problems in the fields of health, environment, medicine and safety. Raman spectroscopy is a suitable method in this context. The measurement data collected in this process are complex and extensive molecular fingerprints. Artificial ...

Making the invisible visible

New method for studying atomic structures in material surfaces

21-May-2021 - Researchers from Friedrich Schiller University Jena, the University of California Berkeley and the Institut Polytechnique de Paris use intense laser light in the extreme ultraviolet spectrum to generate a non-linear optical process on a laboratory scale – a process which until now has only been ...

Unraveling the optical parameters: New method to optimize plasmon enhanced spectroscopy

23-Mar-2020 - For exploring the nanoscale far beyond the optical resolution limit, tip-enhanced Raman spectroscopy (TERS) is widely recognized as an essential yet still emergent technique. Using this marker-free spectroscopic method scientists gain insights into the structural and chemical composition of ...

A quadrillionth of a second in slow motion

Observing and controlling ultrafast processes with attosecond resolution

22-Feb-2018 - Many chemical processes run so fast that they are only roughly understood. To clarify these processes, a team from the Technical University of Munich (TUM) has now developed a methodology with a resolution of quintillionths of a second. The new technology stands to help better understand ...
