What is the main principle of IR spectroscopy?
IR spectroscopy is useful in identifying functional groups in your sample. Many functional groups have specific absorption frequencies, so examination of IR spectra can tell you which functional groups are present (but not where they are structurally in your molecule). A table of common IR absorption frequencies are here: http://www.chem.ucla.edu/~webspectra/irtable.html Most of the time IR is used with NMR to identify a compound. IR can often be used independently to see if a reaction has worked (like if you are adding an azido group to your compound, you can use IR to see if your purified product has an azido absorption).
What is the significance of the FTIR wavenumber in spectroscopy analysis?
The FTIR wavenumber is significant in spectroscopy analysis because it helps identify the specific chemical bonds present in a sample. Different functional groups in molecules vibrate at distinct wavenumbers, allowing scientists to determine the composition and structure of the sample.
What indicator is used to determine a compound?
