Plastics can be divisive since they are convenient and inexpensive, yet have a harmful impact on the environment. These materials are found everywhere – from museums to modern medicine, and even in the ocean waves. Plastic is ubiquitous, and Raman spectroscopy can be used anywhere it is located for identification, classification, and quality testing ...

Resonance Raman spectroscopy is a Raman enhancement technique in which the laser excitation frequency is chosen to be close to the frequency of an electronic transition of the sample. Resonance Raman can enhance the Raman scattering intensity by a factor of 102-106 and improves signal-to-noise. The enhanced Raman scattering means shorter exposure times can be used, allowing much faster spectral ...
In Raman spectroscopy, laser excitation choice is one of the most important considerations. The wavelength chosen will impact Raman intensity, spatial resolution, background fluorescence, acquisition time, and the potential cost of a Raman system. Lasers used in Raman spectroscopy range from the UV into the near-infrared and beyond. Different wavelength regions offer advantages and disadvantages ...
When laser light is focused into a sample by a Raman microscope, a three-dimensional excitation volume is formed within the sample. ...
Confocal Raman microscopy combines the spectral information from Raman spectroscopy with the spatial filtering of a confocal optical microscope for high-resolution chemical imaging of samples. ...
The spectral resolution in Raman spectroscopy dictates the maximum number of spectral peaks that the spectrometer can resolve. The level of spectral resolution required is dependent on the sample and what information the user is aiming to obtain from the Raman spectrum. Five main factors determine the spectral resolution achievable: slit size, diffraction grating, spectrometer focal length, ...
In Raman microscopy, spatial resolution is vital for discriminating different structures in a sample. ...
What is Molecular Spectroscopy?Molecular Spectroscopy is a subcategory of spectroscopy that studies the interaction of radiation with molecules and extended materials, as opposed to atomic spectroscopy techniques which deal with individual atoms. Samples that absorb (UV-vis spectroscopy), emit (Photoluminescence spectroscopy), or in elastically scatter (Raman spectroscopy) radiation may be ...
As Burns Night approached and the people of Scotland were eagerly awaiting their wee dram of whisky, the Applications team wondered what a dram would look like when a laser is shone onto it. For those of you not up to scratch on your Scots knowledge a ‘wee dram’ is the perfect pour of whisky, and on the 25th of January across Scotland we raise a glass to celebrate the life of one of our most ...
