Anomalies in the spectra of the aromatic planar molecule coronene can be explained with powerful calculations on infrared and Raman spectroscopic data. The evidence suggests that minute out-of-plane molecular distortions from D(6h) to C(2h) symmetry are the underlying cause. [February 1, 2010] |

It won't necessarily be music to the classical purist's ear, but chemists have been instrumental in revealing the secret beneath the varnish on a Stradivari violins, and the secret is: there is no secret. [January 1, 2010] |

The appropriateness of near-infrared reflectance spectroscopy for the estimation of stable isotope ratios for nitrogen and carbon of plant tissues has been demonstrated on seven bog species from Patagonia. [December 2, 2009] |

Microwave waveguides on a diamond-based chip can generate a magnetic field large enough to change the quantum state of an atomic-scale defect in less than one billionth of a second, emulating the process involved in magnetic resonance imaging and potentially leading to a new approach to quantum computing.

The application of near infrared spectroscopy for predicting the thermal decomposition behavior of lignocellulosic biomass (three types of woody biomass and three types of herbaceous biomass) was successfully performed along with statistical analysis. [November 2, 2009] |

Near infrared (NIR) reflectance and laser Raman spectra can be used to quickly screen drug samples non-destructively and to spot contamination. The techniques could not displace nuclear magnetic resonance spectroscopy and electrophoresis required by drug regulators, but could be used as a quick first test for screening potentially contaminated drug products.

A method of prediction of tablet properties based on near-IR spectra of raw mixed powders before compression was developed using chemometrical means, allowing for the effect of the difference in scale up using a pilot-scale mixing machine and a continuous tableting machine was studied.

A near-infrared-emitting alloy of cadmium, selenium, and tellurium, has been used to make a novel type of quantum dot that is of high-quality, water-soluble, and biocompatible. The quantum dots might have application in the analysis and study of biological systems. [October 1, 2009] |

The benefits and applications of using mid and far IR reflection spectrometry (IRS) in the analysis of archaeological materials are illustrated and a new IRS database for more than 250 different archaeological minerals and stone materials is presented. [September 7, 2009] |

Spectroscopy, forensic science and even a future generation of quantum communication devices could benefit from research at the National Institute of Standards and Technology (NIST) where a new, highly sensitive, and low-cost approach has been developed for measuring light in the near-infrared range.

Naturally occurring macromolecules present at the epicuticular wax/stalk tissue interface of sugarcane were investigated using near IR spectroscopy alone to study water, cellulose, and wax-cellulose interrelationships, where in the past many different techniques have been required. [August 3, 2009] |

A research team in Spain has used infrared spectroscopy to reveal that taking the temperature of the Red Planet is not quite as straightforward as astronomers would like to think. They have demonstrated that the mineralogical chemistry of the planet's surface can influence the precise temperature readings obtained for Martian soil. [August 1, 2009] |

Hydrogen bonding in a nylon 6/mesoporous silica nanocomposite was investigated using variable-temperature FTIR spectroscopy. Comparison with the results for nylon 6 showed that mesoporous silica increases considerably the thermal stability of hydrogen bonding. [July 3, 2009] |

Understanding future climate change hinges on the analysis of all contributing factors, not least atmospheric aerosols. Now, infrared spectroscopy and mass spectrometry have revealed important clues as to the role of aerosols in affecting climate patterns. [July 1, 2009] |

A rapid and simple instrumental method based on FTIR spectroscopy was developed for simultaneous analysis of Cheddar cheese composition and flavor quality and tested on twelve different Cheddar cheese samples. [June 1, 2009] |
|
The European Southern Observatory's Very Large Telescope now has an X-shooter, a second-generation spectroscopic instrument that can record the entire spectrum of a celestial object in a single shot - from the ultraviolet to the near-infrared - with high sensitivity. [June 1, 2009] |

Urea and water contents in the human stratum corneum were measured coincidentally in vivo after the treatment of urea-containing cream by a Fourier transform near-infrared spectrometer with a fiber-optic probe. [May 4, 2009] |

An international team of astronomers has detected two of the most complex molecules yet discovered in interstellar dust: n-propyl cyanide and ethyl formate. The latter gives raspberries their distinct flavour and has a faint rum-like scent. [May 1, 2009] |
