N2 - Using the analytic Bethe ansatz, we initiate a study of the scaling limit of the quasi-periodic \(D^{(2)}_3\) spin chain. Supported by a detailed symmetry analysis, we determine the effective scaling dimensions of a large class of states in the parameter regime \(\gamma\in(0,\pi/4)\). Besides two compact degrees of freedom, we identify two independent continuous components in the finite-size spectrum. The influence of large twist angles on the latter reveals also the presence of discrete states. This allows for a conjecture on the central charge of the conformal field theory describing the scaling limit of the lattice model.
