Photodissociation dynamics of DNA bases.
In order to access the damaging mechanismsof DNA and its bases on themolecular level by T Hz radiation, it isnecessary to create a database of assessingdamage at different spectral regions.Possible damage by T Hz radiation will beassessed by comparison. Furthermore, theexpose of the cytosine to radiation at157 nm, suggest that photochemical bondbreaking is the only damaging mechanism inthe vacuum ultraviolet region of thespectrum, (157-170) nm where one photonbreaks one chemical bond.
