Experimental study reveals low-frequency Stokes and anti-Stokes Raman spectra in hexagonal ice Ih, highlighting temperature-dependent vibrational dynamics.
Radiation at lambda = 488.0 nm was used to obtain Raman scattering in ice Ih (atmospheric pressure, hexagonal structure). New Stokes spectra were detected for frequency shifts less than 50 cm(-1), and new anti-Stokes spectra were observed for frequency shifts to -212.5 cm(-1). Measurements of total differential Raman scattering cross sections were made for some bands in ice Ih and liquid water. The temperature dependence of the ratio of a pair of Stokes-anti-Stokes lines is given for ice lh.
