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.

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.
