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

Purpose: The purpose of this experiment is to expend the usage of infr ared spectroscopical analysis and to identify the recondite compound # 53 use Fourier-Transform unseeable mass spectrometer. From the IR spectroscopy, particular functional group peaks are say and used to abet the identification of the abstruse quantity constitutional compound. Furthermore, in this experiment, a nonher unknown will be disposed and researched upon its apparitional data. Main Reaction: there is not reaction carried come on in this experiment.

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

Then a background IR was interpreted to aid the clarity of sample IR. The background IR was not added to window to prevent cooccur of the actual sample IR and the air IR. Around 1 drop of unknown liquidness sample was then set on the detector using a capillary dedicate and taken its IR. After the IR graph was obtained, the peaks were assigned and assign using a sceptre line as the boundary. ascertained jot:         - Yellow-orange color         - Almond-like odor Specific Functional Group         Observed Frequency Vibration (cm-)          strength         Shape Aldehyde C-H         2815.92 & 2735.25         Medium         Weak...
