The human eye can only see a small part of the much broader spectrum of electromagnetic radiation (Figure 1). On the high-energy side of the visible spectrum lies the ultraviolet (UV) region, while on ...

An established tool for the authentication and conservation of fine art paintings, Fourier-transform infrared spectroscopy (FTIR) typically requires the removal of small sample sections for analysis.

When measuring the infrared radiation absorbed by a liquid or solid, well-defined regions of absorption can be attributed to the vibrational transitions. Assuming that the resolution of the instrument ...

Infrared spectroscopy, especially for molecular vibrations in the fingerprint region between 600 and 1,500 cm−1, is a powerful characterization method for bulk materials. However, molecular ...
