IR spectroscopy of organometallic ions in the gas phase
Date: Jul 2, 2007
Author:
This review focusses on gas phase IRMPD spectroscopic investigations for probing the structure and the reactivity of transition metal complexes. The performance of infrared spectroscopy for characterizing the coordination mode of polydentate ligands and the spin state of the metal will be illustrated.

Micro lasers... so NIR
Date: Jul 1, 2007
Author: David Bradley
Japanese researchers have built a highly efficient room-temperature NIR laser that produces a stable, continuous stream of NIR laser light. The device overall has a width of just a few micrometres and might find applications in portable NIR spectroscopy and other areas, such as optoelectronics.

Characterization of molecular orientation in PET bottles by external reflection IR spectroscopy
Date: Jun 4, 2007
Author:
The utility of a front-surface reflection IR technique was demonstrated for the characterization and quantification of the molecular orientation at the outer surface of injection-stretch-blow-molded bottles made from PET.

NIR down to earth
Date: Jun 1, 2007
Author: David Bradley
Understanding the devastating effects of wildfire on soils could be down to near-infrared reflectance spectroscopy, according to Spanish researchers. They suggest that a clearer understanding of soil damage could improve efforts aimed at erosion control and regeneration following a fire.

IR and Raman bare toothy problem
Date: May 1, 2007
Author: David Bradley
ATR-FTIR and Raman spectroscopy have confirmed that alternate exposure of the teeth to the antibacterial agent sodium hypochlorite and calcium-chelating EDTA can deplete the organic content of dentine and so seriously degrade the teeth.

Measurement of fatty acids in whole soybeans with near infrared spectroscopy
Date: May 1, 2007
Author:
This discussion summarizes the progression of whole-soybean fatty acid calibration developments at Iowa State University, in the context of plant breeding, with special emphasis on linolenic acid and total saturates.

A novel ATR-FTIR approach for characterisation and identification of ex situ immobilised species
Date: Apr 2, 2007
Author:
A novel method to analyse ex situ prepared protein chips by ATR-FTIR, which circumvents tedious functionalisation steps of internal reflection elements (IREs), simultaneously allows for complementary measurements by other analytical techniques.
