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 ...

Researchers have developed a low-cost method for the analysis of interfacial molecules by combining ATR-IR with precise gap-control and multi-variate data analysis. A novel spectroscopic method ...

Density Functional Theory (DFT) has emerged as an indispensable tool in the study of molecular spectroscopy and structure analysis, providing detailed insights into the electronic and geometric ...

What’s the story behind DNA melting temperature analysis? UV-Visible absorption spectroscopy can be used to assess the characteristics of deoxyribonucleic acid (DNA), a naturally occurring polymer ...

Coupling mid-infrared “idler” photons with near-infrared “signal” photons enables cheaper, smaller and more efficient machines for uses such as greenhouse gas monitoring to medical diagnostics.

Current medical imaging techniques mostly provide information based on morphological or anatomic differences of the tissue, disregarding the underlying molecular composition. Molecular-sensitive ...
