The boson peak is a largely unexplained excitation found universally in the terahertz
vibrational spectra of disordered systems; the so-called fracton is a vibrational excitation …

Infrared (IR) and Raman are two complementary techniques of vibrational spectroscopy both
of which have been used extensively over the years in glass studies. This chapter introduces …

This work illustrates several theoretical fundamentals for the application of THz vibrational
spectroscopy to molecular characterization in the solid state using two different types of …

Terahertz time-domain spectroscopy and low-frequency Raman scattering were performed
on the natural polymer starch to investigate the boson peak (BP) dynamics. In the infrared …

The dispersion properties of the absorption coefficients [α (ν)] of different multi-component
silicate oxide glasses have been studied in the frequency region below the boson peak by …

Terahertz time-domain spectroscopy has been used to extract the light-to-vibration coupling
coefficient for sodosilicate glasses, from which it was possible to calculate the variance in …

Terahertz-time domain spectroscopy () uses the real and imaginary parts of the dielectric
