Mark Tobin and colleagues describe “Fourier transform infrared spectroscopy and imaging of dragonfly, damselfly and cicada wing membranes”. Insects and plants have evolved highly specialised surfaces such as being highly water repellent or superhydrophobic, which also confers self cleaning properties. This is of interest to materials scientists to help in the development of manufactured materials with similar properties. High spatial resolution FT-IR spectroscopy and imaging provide useful information about the complex chemical patterning that contributes to this functionality.

A new technique combines electron microscopy and synchrotron x-rays at Brookhaven Lab to track chemical reactions under real operating conditions.

Karsten Hinrichs and Andreas Furchner describe “Infrared mapping spectroscopic ellipsometry”. Recent developments in fundamental and materials research have increased the value of mapping techniques such as ellipsometry. IR ellipsometry, since it operates in the mid-IR fingerprint region, provides complementary information on composition, structural properties and interactions

In situ spectroscopic methods such as infrared, Raman and UV/vis spectroscopy are powerful tools to gain insight into reaction mechanisms and catalyst actions in homogeneously catalysed reactions. These methods and combinations of them offer great potential for the real-time monitoring of reactions in the liquid phase, for mechanistic studies as well as process control and kinetics.

Thermo Scientific


Hand-held spectrometer that combines both FT-IR and Raman spectroscopies in a single instrument. Libraries are included to enable operators to identify unknowns ranging from explosives and chemical warfare agents to industrial chemicals and precursors. Switching between the two techniques is quick and is done via either the keypad or touchscreen. A motorised anvil adjusts sample pressure based on user settings for FT-IR analysis. Built-in safety features including a scan delay also increase protection from potentially hazardous substances.

IR spectroscopy is a useful tool for group chemical species identification of a wide variety of sample materials, particularly for the classification of “organic” chemical materials based upon carbon atoms being present in the molecular structure. Many plastic and polymeric type samples which can be included in the category of organic molecular materials can be classified into particular “family” groupings and it is possible to identify the sample family types both qualitatively and quantitatively by use of the Attenuated Total Reflectance (ATR) technique as an IR measurement. (See - Specac Application Note 42).
