We have studied the impact of excitation laser power density on the Raman spectrum of small-diameter (5−15 nm) silicon nanowires. At low power densities, a Lorentzian line is observed at 520 cm-1, the same value as that of the zone center LO (TO) phonon in bulk silicon. With increasing laser illumination, the Raman band downshifts and asymmetrically broadens on the low-frequency side. Our

Infrared: Appliion - Chemistry LibreTexts

Each band in a spectrum can be attributed to stretching or bending mode of a bond. Almost all the fundamental vibrations appear in the mid-infrared region. For instance, 4000 – 2500 cm -1 region usually can be assigned to stretching modes of O-H, N-H or C-H. Triple-bond stretching modes appear in the region of 2500 – 2000 cm -1 .
