View Benzocaine Ir Spectrum Background. Severalimportant peaks in the ir spectrum of benzocaine (figure 3, supplemental data) were used toidentify the product as benzocaine. .ir bands in the spectrum above and identify corresponding bonds/functional groups in benzocaine molecule.

• ir spectrum of menthone (fig 12.12).

These include the absence of the bump at 3660 on benzocaine's spectrum that is there on the starting material's spectrum. In part 1 of this experiment, you will compare and contrast actual ir spectra of a variety of different compounds and. Yesterday, after lab, she gave us some ir spectra and told us to understand which organic molecule is hidden behind it. In ir spectroscopy, a molecule is irradiated with electromagnetic radiation.
