The efficacy of far-IR spectroscopic characterization of pigment materials has been shown for macro samples. 12-15 The far-IR microspectroscopy study of pigments, however, has been an untapped field ...

We analyze here a wide sample of carbonaceous chondrites from historic falls (e.g. Allende, Cold Bokkeveld, Kainsaz, Leoville, Murchison, Murray and Orgueil), and from NASA Antarctic collection in ...

FTIR deals with the infrared region of the electromagnetic spectrum, and it works by measuring how much light is absorbed by the bonds of vibrating molecules to provide a molecular fingerprint. The ...

A spectrometer that directly detects the vibrational “fingerprint” of molecules offers a sensitive new way of deducing a material’s chemical make-up. The device, which was developed by researchers in ...

Light is an electromagnetic wave: it consists of oscillating electric and magnetic fields propagating through space. Every wave is characterized by its frequency, which refers to the number of ...
