Infrared spectroscopy studies mainly molecular spectra, since most of the vibration and rotation spectra of molecules lie within the IR region. The study of the IR absorption spectra that arise as a result of the absorption of IR radiation as it passes through matter is used most widely in ...

Camouflage textiles can be detected by human eyes (Vis) or instrumental investigations such as spectroscopy, microscopy, digital cameras and hyperspectral cameras. The reflectance profile of a target signature (camouflage textiles) can be matched with the reflectance profile of CB in the vein of ...
Can I use the iC IR software to analyze experimental data on another computer? How can I get iC IR experiment data into other systems such as my ELN or data warehouse? Can I show data from other iC instruments in iC IR? What are the computer requirements to run iC IR software?
FT-IR spectroscopy The IR spectrum plays an important role and provides valuable information related to the functional groups in pentacyclic triterpenoids. IR spectra of triterpenoids have two characteristically regions. Absorption bands in the region 3500–3650 and 2650–3350 cm− 1 are due to OH...
