In this work, a broad pallete of macroscopically sized samples ionic liquids was used, in which tensions about -100 MPa were obtained preliminary testing methodologies before cavitation would occur. Preliminary NMR studies have been performed on under homogeneous tension. Upon entering into these metastable regimes negative pressure, it is possible to observe sharp increase the anion and cation self-diffusion coefficients as compared equilibrium saturated liquid conditions at identical temperatures.
