Abstract: (Elsevier)
We project out from the finite-size scaling spectra of the XXZ model, the spectra of various systems with c < 1. Through this projection we get the operator content corresponding to various charge sectors and boundary conditions. This is one step further than the knowledge of the modular invariant partition functions. We also show how the projection mechanism works for finite chains.- STATISTICAL MECHANICS: TWO-DIMENSIONAL
