BALUJA, Shipra  e  LAVA, Divyata. Ultrasonic behavior of various chalcones in some solvents at different temperatures. Rev. colomb. cienc. quim. farm. [online]. 2016, vol.45, n.3, pp.339-361. ISSN 0034-7418.  https://doi.org/10.15446/rcciquifa.v45n3.62014.

Ultrasonic velocity, density and viscosity of some synthesized chalcones were measured in N,N-dimethyl formamide and chloroform at different temperatures (298.15 to 318.15 K). From these experimental data, various acoustical parameters such as specific impedance (Z), adiabatic compressibility (k_s), Rao's molar sound function (R_m), intermolecular free path length (L_f), solvation number (S_n), internal pressure (Π) have been calculated in order to understand the molecular interactions in the studied solutions. The results are interpreted in terms of molecular interactions occurring in the solutions.
