EXAMPLE:

Unknown Identification through a Boiling Point Determination & Infrared Spectroscopic Analysis

An unknown organic compound was identified from a database of possible structures employing a combination of a boiling point determination followed by analysis of the infrared spectrum. Over three trials, the boiling point of the unknown liquid was measured across a range spanning from 199-205 ^oC with an average value of 203 ^oC & a relative range of 3%. Analysis of the IR spectrum revealed four characteristic signals at 1704 cm^-1, 2734/2837 cm^-1, 2963 cm^-1 & 3031 cm^-1 corresponding to a conjugated carbonyl, aldehyde C-H bond, sp³ C-H bonds and sp² C-H bonds, respectively. Based on these results, the identity of the unknown organic compound is 4-methylbenzaldehyde, which displays a literature boiling point of 204 ^oC (0.5% error). The most likely alternative, benzyl alcohol, was ruled out based on the absence of a broad signal in the IR spectrum at 3500 cm^-1.
