To help make your job easier, we outlined the basic organic functional groups, their positions of infrared bans, their relative peak intensities, and their functional group representation. Download this easy-to-readchart. Looking for more basic FTIR information, be sure to visit ourFTIR Spectros...
With FTIR testing, the light is measured using an infrared spectrometer which produces the output of an infrared spectrum. The FTIR spectrum is displayed as a chart. The vertical axis shows how much infrared light the substance absorbs. The horizontal axis represents the frequency, or wavelength, ...
Since every functional group is composed of different atoms and bond strengths, vibrations are unique to functional groups, and classes of functional groups (e.g. O-H and C-H stretches appear around 3200 cm-1and 2900 cm-1, respectively). A correlation chart with various functional group vibr...
Note from our chart that a molecule behaves differently when exposed to these different energy levels. For example when exposed to x-ray energy a molecule will undergo nuclear transitions (i.e.. lose a neutron) or when exposed to ultraviolet energy it may undergo an electronic transition (i....
The spectra obtained were interpreted and analyzed with the aid of structure correlation chart. A visual basic computer program was developed based on the data analyzed and experience gained.Results: The results revealed that the biodiesel contained fatty acid methyl esters (FAME). The FTIR spectrum...
The data volume was intentionally limited so as not to overload the chart while at the same time giving the widest possible range of panel thickness. It can be clearly seen that the isocyanurate/phenyl ratio of all PIR foams dramatically increases from the surface toward the core of the foam...

3.1. The Lollipop Chart To summarize a large amount of data (746 spectra) in a visually interpretable form, the lollipop chart [35] has been employed. The lollipop chart functions identically to a normal bar plot, visually consisting of a line anchored at the x- or y-axis and a dot at...
