| Abstract: | A high-resolution ac calorimetry measurement of the nematic to smectic-A transition has been carried out carefully on octyloxycyanobiphenyl (80CB). The measured critical exponents α = α′ = .24 ± .03 are consistent with X-ray results through the hyperscaling relation ν∥ + 2ν⊥ = 2 - α. |
