✦ Synopsis

In the framework of the two-dimensional Kondo lattice model with hoppings between first-, second-, and third-nearest neighbors the spin-polaron spectrum is investigated. A complex structure of a spin-polaron and an increase of frustration in spin subsystem leads to the evolution in the excitation band close to the evolution on hole hopping which is given by ARPES experiments in HTSC.

## Abstract The results of the direct analysis of the ABX spin system present in two symmetrical diphosphonates containing a single vinylic ^13^C nucleus are presented. This allows a comparison to be made with the two‐dimensional methods used by Beckmann __et al.__ Significant differences are found
