The resulting bulk conformal weights extend previous exact results obtained in the honeycomb limit and include the negative spectral parameter regimes. The results give the operator content of the 19-vertex Izergin-Korepin model along with the conformal weights of the dilute AL face models in all four regimes.It is a pleasureto thankO le Warnaarfo r helpfuld iscussionosv erthe years.T his work has been supportedb y the AustralianR esearchC ouncil.Y.K.Z. also thankst he Natural ScienceF oundationo f China for partial support.19enConformal dimensionsCritical phenomenaExactly solved modelsFinite-size corrections1997-02-1010.1016/S0550-3213(96)00654-20031561999
