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 ...

Photothermal AFM-IR combines atomic force microscopy and infrared spectroscopy to reveal chemical heterogeneity and structural features at the nanoscale.

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 ...
