All fibers were analyzed directly without additional modification or sampling accessories. The O-PTIR spectra resemble transmission-like IR spectra in non-contact (far-field) mode. Through spatially ...

The sample preparation before conducting an infrared spectroscopy (IR) study is as critical as the study itself, and the samples which are difficult to dissolve in any IR-transparent solvent are mixed ...

IR spectroscopy, or infrared spectroscopy, is an analytical technique used to identify and study chemical substances based on their interaction with infrared radiation. It measures the absorption of ...

Infrared and Raman spectroscopies can observe different types of molecular vibrations. Using both methods on a compound provides a more complete molecular picture than either alone. But the two ...

Definition: Fourier Transform Infrared (FTIR) Spectroscopy is a highly specialized type of IR spectroscopy. It's the most common way IR measurements are carried out today. FTIR is known for its speed, ...

Research into spectroscopy in the mid-IR spectral region has made several recent breakthroughs, spurred by potential uses of the technique in biophotonics and medical imaging. But development of ...

Photothermal AFM-IR, or AFM-IR, is an analytical method used for chemical identification in a materials sample at the nanoscale. AFM-IR incorporates both the nanoscale spatial resolution of atomic ...
