Raman optical activity, long thought to require chiral molecules or magnetic order, has been demonstrated in an achiral, ...

At its simplest, Raman spectroscopy is a light-scattering technique. When monochromatic light, usually from a laser, hits a sample, most of it returns unchanged. But a small portion scatters ...

Raman spectroscopy can be combined with optical confocal microscopy to generate a new analytic technique called Raman microscopy. Light microscopy has several advantages: it can be used to observe ...

Fluorescence spectroscopy has great sensitivity, allowing scientists to detect signals from single molecules. But it has limited chemical specificity, making it hard sometimes for researchers to ...

Researchers from IIT (Banaras Hindu University) have demonstrated that carrot pigment can be added to pig fat or palm oil to ...

Utilizing terrain mapping in Raman imaging ensures optimal focus on uneven samples, enhancing Raman intensity and spatial ...

The TR-A100 Raman plastic analyzer uses non-destructive laser technology to molecularly identify materials. Widely used ...

Laser wavelength selection, a critical determinant of accuracy and data quality, is guided by factors such as resonance, fluorescence, and sample absorption. Ensuring the correct laser wavelength ...
