Abstract
An ac technique has been used to measure the heat capacity near the nematic-smectic A (N-SmA) transition in 8CB along isobars at 1, 750 and 1 500 bar. As the pressure is increased, the magnitude of the Cp peak associated with this transition decreases but the shape of the peak remains essentially unchanged. The excess heat capacity at 1 atm. is consistent with a second-order N-SmA transition characterized by an effective critical exponent α = 0.30 ± 0.05This publication has 12 references indexed in Scilit:
