Ir spectroscopy table a level
WebFTIR stands for “Fourier transform infrared” and it is the most common form of infrared spectroscopy. All infrared spectroscopies act on the principle that when infrared (IR) radiation passes through a sample, some of the radiation is absorbed. The radiation that passes through the sample is recorded. Because different molecules with their ... WebCompare the infra-red spectra of propan-1-ol and propan-2-ol. Both compounds contain exactly the same bonds. Both compounds have very similar troughs in the area around 3000 cm -1 - but compare them in the fingerprint region between 1500 and 500 cm -1. The pattern in the fingerprint region is completely different and could therefore be used to ...
