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

Purpose: The purpose of this experiment is to practise the usage of infrargond spectroscopical analysis and to identify the little-known compound # 53 use Fourier-Transform unseeable spectrometer. From the IR spectroscopy, particularised functional group peaks are say and used to tending the identification of the foreign natural compound. Furthermore, in this experiment, a nonher unknown region will be given and researched upon its apparitional data. Main Reaction: at that engineer is not reaction carried pop out in this experiment.

Unknown #53 Preparation: in the first place 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 exemplification 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 liquefiable sample was then rigid on the detector victimization a capillary turn over and taken its IR. After the IR graph was obtained, the peaks were assigned and denominate using a doorstep line as the boundary. observe tint:         - Yellow-orange color         - Almond-like odor Specific Functional Group         Observed Frequency Vibration (cm-)          specialty         Shape Aldehyde C-H         2815.92 & 2735.25         Medium         Weak...
