| Outline of Final Research Achievements |
The program that calculates ab initio energy band structures of polymers adapting the helical symmetry was developed, and we calculate those of the polymononucleotide and the polydinucleotide. The polymononucleotide consisting with the guanine and cytocine base pairs is significantly interesting. The valence band top is found to move from the gamma point to zero point that is not true for that consisting with the adenine and thymine base pairs.
Furthermore, the difference between the electronic structures of the double helics and the single helics are calculated and discussed the role of the hydrogen bonds between the base pairs.
