Unless you tried a number of liquids to arrive at that conclusion (Kerr
constant) it would seem not to be justified by just comparing
nitrobenzene, which is very reactive -- with water, which is not very
reactive.
The more likely explanation IMHO would involve sonochemistry --and the
exothermic reduction of C6H5NO2. Phenyl groups are notoriously reactive
and sonochemistry is notoriously efficient.
