Line-widths of light scattered by nitrobenzene-heptane system are measured over a wide temperature range including the vicinity of the critical temperature of separation. The critical exponents are measured. Noncoincident value of the critical exponent for the states of the system above and below the critical temperature of separation are obtained.
