Hennig's holomorphology concept defines taxonomy as a process that synthesizes evidence from all relevant comparative sources. One possible source is metabolomics, in which the global metabolic profile is analyzed. An integral metabolic profile can be quickly obtained, nondestructively, through spectroscopy in the near infrared region. Here we use near infrared spectroscopy and chemometry to identify nine species of flies in the genus Neodexiopsis Malloch (Muscidae, Diptera). This genus is the most species-rich of the Muscoidea in the Neotropical region. Identification success demonstrates that near infrared spectroscopy may provide a new source of data to test and organize hypotheses of species delimitation. Comparing near infrared spectroscopy with DNA barcoding, spectroscopy may have even greater conceptual merit as a true barcode of life.

Abstract A new method for the determination of cis and trans-1,4 units in synthetic polyisoprenes and gutta-rubber mixtures has been developed. The method uses the near infrared region of the spectrum and gives better, more reproducible results than the one using the normal infrared region.

Food safety may be one of the major concerns of the global society in the forthcoming decades. Analytical vibrational spectroscopy is expected to become a major tool used for controlling the food quality at every stage of its production, storage and delivery. Near-infrared and infrared spectroscopy have rapidly been evolving in analytical applications over the last decades with strong hyphenation to numerical and statistical methods of analysis of complex data, which are known as chemometrics. Analytical spectroscopy has reached a remarkable value for both industrial and institutional laboratories nowadays. However, the routinely used methods of analysis do not attempt to interpret the analysed spectral information in physicochemical sense. Therefore, analytical routines seldom take advantage of the molecular background underlying the properties of analysed sample. In the present article, we review the most recent accomplishments that evidence the progress which may be achieved when that background becomes actually available. We focus on the example of infrared and near-infrared spectra simulation applied to melamine, one of the most infamous food adulterant. This sheds light on the correspondences between infrared and near-infrared region observed earlier in the analytical papers dealing with detection and quantification of melamine in food products.

The variations in temperature during the analysis of alcoholic beverages are of importance to develop protocols based on near infrared spectroscopy. The objective of this study was to evaluate the effect of increasing temperature on the near infrared spectra of whisky samples using two-dimensional correlation spectroscopy. Whisky samples from different commercial labels were analyzed at four different temperatures (25°C, 35°C, 45°C, and 55°C) using a UV–VIS–NIR instrument. Asynchronous and synchronous two-dimensional correlation spectroscopy was used to reveal the effect of temperature on the near infrared spectra of the samples. The results of this study indicated that temperatures between 40°C and 55°C alter absorption at specific wavelengths in the near infrared region of the whisky samples analyzed. The combination of near infrared spectroscopy with two-dimensional correlation spectroscopy has the potential to dramatically improve the efficiency of analytical laboratories, considering the range of data that can be collected.
