| Abstract |

|
|
| Using the BLYP DFT crystal orbital method for 19 homopolypeptides in their beta pleated sheet conformation their band structures were calculated. The position of the conduction and valence bands, their widths and their fundamental gap values are very similar to the previous simple LDA DFT results. This indicates that without the elimination of the self-interaction error one cannot obtain realistic gap values. The B3LYP calculations, which are in progress, most probably will increase the too small gap values because of the inclusion at least a part of the exact HF exchange. However, one expects that a DFr method tailored for the calculation of excited states and gaps of periodic polymers will bring a satisfactory solution of the problem. (C) 2003 Elsevier B.V.
