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.
8-Bromocaffeine. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). 8-Bromocaffeine is a derivative of caffeine (a xanthine class), which is used as a radiosensitizer in the radiotherapy of tumors to increase the sensitivity of tumor cells to radiation treatment.
21 Οκτ 2024 · After completing this section, you should be able to use an infrared spectrum to determine the presence of functional groups, such as alcohols, amines and carbonyl groups, in an unknown compound, given a list of infrared absorption frequencies.
The NIST Quantitative Infrared Database currently consists of a collection of absorption coefficient spectra of volatile organic compounds. These spectra were measured from primary gas standards prepared and verified at NIST.
Understanding the IR spectrum of caffeine can have significant implications for health and wellness. By analyzing the peaks and absorption bands, researchers can gain insights into the purity, stability, and structural characteristics of caffeine-containing products.
16 Δεκ 2021 · With the basic understanding of the IR theory, we will take a look at the actual output from IR spectroscopy experiments, and learn how to get structural information from IR spectrum. Below is the IR spectrum for 2-hexanone.
