Scientists at Baltic Federal University have suggested evaluating concentration and chemical composition of drugs by means of vibrational spectroscopy and nuclear magnetic resonance instead of ...

Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at surfaces and interfaces, but its spatial resolution has been limited to the ...

A paper titled "Tip-enhanced sum frequency generation spectroscopy using temporally asymmetric pulse for detecting weak vibrational signals," published on February 19, 2026 by a research team from the ...

A more notable feature of SFG spectroscopy is its surface specificity and absolute up/down molecular orientation sensitivity, allowing discrimination between up- and down-oriented molecular ...

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.

Vibrational spectroscopy is a high-performance analytical technique commonly used in chemistry, materials science, biology, and environmental research. Infrared spectroscopy (IR) is the most ...

Raman spectroscopy is a type of vibrational spectroscopy that relies on Raman scattering to deduce the vibrational, rotational and other low-frequency modes of different molecules. Once the ...

Lithuanian researchers at the Center for Physical Sciences and Technology (FTMC), Habil. Dr. Gediminas Niaura and Dr. Martynas Talaikis, together with international colleagues, have for the first time ...

Vibrational spectroscopy, a technique essential for analyzing chemical components in biological compounds, cells, organisms, tissues, and bioactivity products, plays a significant role in various ...

Raman spectroscopy is an analytical characterization technique which has been around for many decades. Since it’s first inception to build a database of molecular vibrational frequencies, it has ...
