In this technique, overtones are false signals that appear at twice the amount of a very strong signal.
In this technique, overtones are false signals that appear at twice the amount of a very strong signal. Aldehydes are easily identified by this technique due to bumps on the right hand side of the alkane peak. This technique detects stretching and scissoring of bonds in water molecules. Its results are plotted in a wavenumber vs. (*) transmittance graph that typically contains a large peak around 3000 indicating carbon-hydrogen bonds. Solid samples for it can be mixed with potassium bromide and pressed to form a transparent disk. With this technique, every molecule has a unique signature between 500 and 1500 inverse centimeters called the fingerprint region. For 10 points, name this technique that probes samples using light at a wavelength longer than visible light.
