Webb26 juni 2024 · Near-infrared (NIR) spectroscopy occupies a specific spot across the field of bioscience and related disciplines. Its characteristics and application potential differs from infrared (IR) or Raman spectroscopy. This vibrational spectroscopy technique elucidates molecular information from the examined … WebbThe spectra in the nir region however, are overtones and combination bands as mentioned earlier and mainly arise from stretching of O-H (water, alcohol) , C-H (fats, oils and hydrocarbons) and N-H (proteins). These absorption features are broadened as compared to their counterparts found in the mid-IR region.

WebbNear-infrared absorption bands originate from overtones and combinations of the fundamental (mid-infrared) bands (mostly from C-H, N-H, and O-H bonds), making FT-NIR spectroscopy especially sensitive to hydroxyl groups as ... Moisture content in lyophilized Leucovorin Ca. overtone and combination regions (Figure 3). Figure 1, Antaris FT-NIR ... Webb24 maj 2024 · NIRS can be used to detect overtones and combination bands of molecular vibrations. Typical vibrations in organic molecules for functional groups include -CH, -NH, -SH and -OH, with -OH moiety being a particularly strong near infrared absorber. Because of this, NIRS has found a central role in moisture quantification applications. sheriff\u0027s hope team
