Experiment 1: IR Unknown/Spectroscopy Assignment FOURIER-TRANSFORM INFRARED SPECTROSCOPY

Purpose: The purpose of this experiment is to practice the usage of infrared spectroscopic analysis and to identify the noncitizen compound # 53 using Fourier-Transform unseeable Spectrometer. From the IR spectroscopy, specific functional separate peaks are say and used to aid the identification of the cabalistic organic compound. Furthermore, in this experiment, a nonher unknown will be given and researched upon its apparitional data. Main Reaction: There is not reaction carried out in this experiment.

Unknown #53 Preparation: in the first place collecting either data, the selected unknown attempt was observed in its color and smell. Then, the Fourier-Transform unseeable Spectrometer detector was cleaned with CH2Cl2 and wiped dry.

Then a background IR was taken to aid the clarity of judge IR. The background IR was not added to window to prevent co-occur of the actual sample IR and the air IR. Around 1 drop of unknown liquid sample was then located on the detector using a capillary render and taken its IR. by and by the IR graph was obtained, the peaks were assigned and denominate using a threshold line as the boundary.
