Abstract

A compact fiber-optic probe for combinational vibrational spectroscopy was developed and evaluated. The probe is capable of simultaneous acquisition of mid-infrared ATR and Raman spectra from the same spot in the region 3100-2600 cm-1 which contains predominantly the responses of C-H stretching vibrations of hydrocarbon residues that has been widely employed in organic, analytic, biological, and polymer chemistry.
