The optical IR spectroscopy combined with Raman spectroscopy is based on interactions between photons and molecular vibrations. The IR spectrum is the fingerprinting of both smaller and larger (bio)molecules. The conventional and sophisticated IR/Raman spectrometers utilize the unique properties of laser light sources.

IR Spectroscopy Tutorial: Alcohols. Alcohols have characteristic IR absorptions associated with both the O-H and the C-O stretching vibrations. When run as a thin liquid film, or "neat", the O–H stretch of alcohols appears in the region 3500-3200 cm-1 and is a very intense, broad band. The C–O stretch shows up in the region 1260-1050 cm-1.

Fourier Transform Infrared spectroscopy[14] FT-IR spectra of clotrimazole beta-cyclodextrin solid dispersions were obtained by Perkin-Elmer FT-IR spectrophotometer using potassium bromide (KBr) pellets. KBr pellets were prepared by gently mixing the sample with KBr (1:100). The sample was scanned from 4,000 to 400 cm-1.

requires absorbance to observed by sequentially scanning through IR bandwidth. both the sensitivity and resolution are increased compared to traditional IR. FTIR is much slower than traditional IR . 15) A primary difference between UV/vis spectroscopy and Atomic Absorption spectroscopy is: a) analytes must be aqueous soluble for UV/vis spectroscopy

Infrared (IR) spectra were recorded in transmission mode in the 4000-370 cm-1 energy range with a Bruker Tensor 27 FT-IR spectrophotometer. 1% of sample was pelletized in KBr. All the spectra were collected with a 4 cm-1 resolution from 100 scans. The data were analyzed using the OPUS software. The background (KBr pellet) was subtracted in all ...
