When analyzing an IR spectrum, it is helpful to overlay the diagram below onto the spectrum with our mind to help recognize functional groups. Figure 1. Group frequency and fingerprint regions of the mid-infrared spectrum. The region of the infrared spectrum from 1200 to 700 cm-1 is called the fingerprint region.
The IR spectrum of caffeine offers a wealth of information about its molecular structure and characteristics. By understanding the peaks and absorption bands, researchers can gain insights into the purity, stability, and therapeutic potential of caffeine-containing products.
Greater swelling and drug release were observed at pH 4.6 and 7.4 as compared to pH 1.2 due to the deprotonation and protonation of functional groups of alginate and 2-acrylamido-2 ...
Caffeine | C8H10N4O2 | CID 2519 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more.
11 Φεβ 2023 · The IR spectrum is a graph where the x-axis is frequency and is labeled as wavenumber (cm-1). The y-axis is the amount of light absorbed and labeled as Transmittance (%). This is measuring how much light has been transmitted at a particular frequency.
Infrared Spectrum of Caffeine. Click on the peaks in the spectrum to see the molecular vibration they corresponds to. The ball and stick molecule can be rotated. All vibrational modes are included in both the stretching and bending regions.
