Abstract

In a recent paper, Cutroni and Mandacini [J. Chem. Phys. 114, 7124 (2001)] measured sound velocities and absorption coefficients in m-toluidine by an ultrasonic technique. They reported velocities that differ from previous published data and attributed some of these discrepancies to a possible difference between the local temperature which actually prevails at the place where the velocity is determined in these previous measurements, and the real temperature of the liquid. We compare their results with other data and discuss their assumption.
