Abstract

The system C $S_{2}$ + C $H_{3}$ N $O_{2}$ shows $β = 0.315 \pm 0.004$ over $10^{- 6} < ε = \frac{| T - T_{c} |}{T_{c}} < 2 \times 10^{- 1}$ with no indication of a classical value ½ even far away from $T_{c}$ . The diameter shows a curvature and is of the form $ϕ_{c} + b ε + f ε^{\frac{7}{8}} \exp (- g ε^{h})$ .
