A student wanted to determine the color components of a black marker ink and describe the behavior of each one. He performed paper chromatography using a cellulose-based filter paper as the stationary phase and carbon tetrachloride as the mobile phase. Based on the resulting chromatogram, there were four colors separated. He then measured the distance traveled by each component. The table below shows the data that he obtained: Distance Dye Distance Solvent Color Moved Rf value Moved (mm) (mm) Orange 50.0 14.0 Green 50.0 7.0 Red 50.0 23.5 Blue 50.0 35.5
Analyzing Infrared Spectra
The electromagnetic radiation or frequency is classified into radio-waves, micro-waves, infrared, visible, ultraviolet, X-rays and gamma rays. The infrared spectra emission refers to the portion between the visible and the microwave areas of electromagnetic spectrum. This spectral area is usually divided into three parts, near infrared (14,290 – 4000 cm-1), mid infrared (4000 – 400 cm-1), and far infrared (700 – 200 cm-1), respectively. The number set is the number of the wave (cm-1).
IR Spectrum Of Cyclohexanone
It is the analysis of the structure of cyclohexaone using IR data interpretation.
IR Spectrum Of Anisole
Interpretation of anisole using IR spectrum obtained from IR analysis.
IR Spectroscopy
Infrared (IR) or vibrational spectroscopy is a method used for analyzing the particle's vibratory transformations. This is one of the very popular spectroscopic approaches employed by inorganic as well as organic laboratories because it is helpful in evaluating and distinguishing the frameworks of the molecules. The infra-red spectroscopy process or procedure is carried out using a tool called an infrared spectrometer to obtain an infrared spectral (or spectrophotometer).
