Here’s the best way to solve it. Answer:- 1685cmIn contrast, the right half of the spectrum, below 2000 cm-1, normally contains many peaks of varying intensities, many of which are not readily identifiable. Two signals which can be seen clearly in this area is the carbonyl group, which is a very strong peak around 1700 cm-1, and the C-O bond with can be one or two strong peaks around 1200 cm-1.Given the data presented by Roy and co-workers, it is difficult to assess this peak as a choice for a reference band as the transmission FTIR spectrum, shown in their paper, suggested oversaturation of the C–H and C═O bands and poor baseline resolution; additionally, there are many examples of transmission PE spectra that do not contain …

In the FTIR spectra of formulation containing both norfloxacin and C934, the prominent band, found between 3550 and 3400 cm -1, was assigned to υO–H and polymeric hydrogen bonding [ Figure 5 ]. The peak at 2600–2500 cm -1 represented the υO–H of carboxylic acid, i.e., strong intermolecular hydrogen bonding.Hydroxide contamination peak is due to the reaction with residual water in the lab air or the vacuum. The O (1s) BE of the hydroxide (water) contamination normally appears 0.5 to 1.0 eV above the oxide peak. Sodium (Na), Potassium (K), Oxygen (N) and Oxygen (Cl) are common trace to low level contaminants.This strategy places a C O peak at 531.2–531.6 eV with an aliphatic C O group positioned at 532.5–532.9 eV and aromatic C O positioned near 533.0–533.4 eV. These positions are consistent with those reported by other groups [54]. The assignment of adsorbed moisture and oxygen is variously assigned between 533 and 535 eV.
