Unravelling the non-covalent interactions in certain n-propyl amine – Ether systems through acoustic and DFT studies at 303.15 K

Ultrasonic study of four binary liquid mixtures, containing n-propyl amine (NPA) as the common component and four structurally different ethers [tetrahydrofuran (THF), 1, 4 dioxane (DIOX), anisole (ANI) and diphenyl ether (DPE)] as varying components is carried out over the entire mole fraction range at 303.15 K and at experimental pressure of 101 kPa. The acoustical and excess thermo acoustic parameters reveal the existence of H-bonded...
