INVESTIGATION OF THE ACOUSTIC PROPERTIES OF AQUEOUS γ-PICOLINE SOLUTIONS BY TANDEM MANDELSTAM-BRILLOUIN SPECTROSCOPY
This paper presents the results of a study on the acoustic and elastic properties of aqueous γ-picoline solutions in the concentration
range from 0.005 to 0.10 mole fractions using tandem Mandelstam-Brillouin spectroscopy. Analysis of the experimental data shows
that the addition of γ-picoline leads to a non-linear increase in hypersonic velocity and bulk modulus, accompanied by a decrease
in adiabatic compressibility
