^aThe listed data are averaged from 12 measured echo-delay times (4 sets of 3 replicates each); see Supporting Information for unaveraged data. The data are listed in the order measured; blank lines separate measured isochores.

^bThe standard (k = 1) uncertainties in T and p are 0.005 K and (26 × 10^–6p + 0.016 MPa), respectively.
