Infrared absorption spectrum

In the present study extracellular polysaccharide (EPS) was characterized from Pseudomonas aeruginosa B01. EPS was purified using ethanol precipitation and dialysis. The purified EPS from P. aeruginosa B01 was analyzed using a High Performance Liquid Chromatography (HPLC). The infrared spectra of EPS from P. aeruginosa B01 clearly showed the presence of carboxylate groups. The FT-IR spectrum indicated an intense absorption band in the region of 3296 cm-1 on the stretching vibration of hydroxyl groups (OH).

Chapter 12 - Infrared spectroscopy and mass spectrometry. This chapter identify the reliable characteristic absorptions in an infrared spectrum, and propose which functional groups are likely to be present in the molecule; explain which functional groups cannot be present in a molecule because their characteristic peaks are absent from the IR spectrum; use a mass spectrum to determine a compound’s molecular weight, and propose which elements are likely to be present;...
