Mid infrared gas spectroscopy using efficient fiber laser driven photonic chip-based supercontinuum

open access: yesNature Communications, 2019
The mid-infrared spectral region is important for gas sensing applications. Here, Grassani et al. demonstrate efficient supercontinuum generation from fibre-lasers injected into silicon nitride waveguides to provide a turn-key mid-IR source with ...

Structural insights of asphaltenes through mild oxidation reactions and MID infrared spectroscopy

open access: yesCT&F Ciencia, Tecnología & Futuro
Mild oxidation reactions were induced over four different asphaltenes. Oxidation products were characterized via infrared spectroscopy to propose structural descriptors, taking advantage of the high sensitivity for detecting carbon oxygen vibrations in ...

Femtosecond mid-infrared spectroscopy of water

open access: yes, 2002
The recent availability of intense femtosecond pulses at wavelengths near 3 μm has enabled a new form of time-resolved spectroscopy that allows for a real-time measurement of the ultrafast dynamics of individual water molecules. In this chapter, an overview is given of the new information that has been obtained with this technique on the vibrational ...
