What are Combination Bands?
Combination bands occur when two or more molecular vibrations are excited simultaneously, producing absorption features at unique wavelengths within the near-infrared region. Together with overtone bands, combination bands provide much of the chemical information used...What are Overtones?
Overtones are higher-order molecular vibrations that occur at multiples of a fundamental vibrational frequency. In near-infrared (NIR) spectroscopy, overtone absorptions are much weaker than the corresponding fundamental absorptions observed in the mid-infrared...What is Chemometrics?
Chemometrics is the application of statistical, mathematical, and machine learning techniques to spectral data in order to identify materials, quantify chemical constituents, and predict sample properties. By analyzing subtle spectral patterns, chemometric models...What are accessories?
Due to the modular nature of our instrumentation, one spectrometer can potentially be used for many applications. All StellarNet spectrometers are designed to work with different light-collecting accessories. These accessories set up proper geometry for each...What is the ChemWiz Concentration Predictor?
The ChemWiz Concentration Predictor makes use of the Beer-Lambert law (see absorption spectroscopy) to predict the concentration of unknown samples. It can be accessed by clicking “Applications” > “ChemWiz Methods,” “Chem,” or the chemistry glassware icon. By...
