Relaxation timeIntermolecular interactions.The density (ρ), refractive index (n_D), dielectric constant (ε_s) and relaxation time (τ) of binary mixture of allyl bromide with polar protic solvent n-butanol including those of the pure liquids, were measured over the complete composition range. ...
3. “Protic” Solvents Have O-H or N-H Bonds And Can Hydrogen-Bond With Themselves. “Aprotic” Solvents Cannot Be Hydrogen Bond Donors There’s a final distinction to be made and this also causes confusion. Some solvents are called “protic” and some are called “aprotic”. What makes ...
These colored photomerocyanines have an important polar character in the ground state (negative solvatochromism) and are stabilized bypolar solvents(protic or aprotic), i.e. the thermal fading rates strongly decrease. The electronic distribution looks like a dipolar or zwitterionic one, the dipolar ...
