| Research Abstract |
In this study, soft X-ray spectroscopy calculations are applied to biomolecular systems. Two computational methods are constructed; one is X-ray natural circular dichroism (XNCD) which is one of specific for biomolecules, the other is double core hole (DCH) spectroscopy which is specially forcus in the use of X-ray free electron laser. For XNCD, a new code has been developed and is applied to several amino acid using cluster models. Our calculations for alanine are consistent with the experiments. For DCH state calculations, we performed calculations for nucleobases, and our calculations can be induced information reflected with chemical environment of molecules.
