The investigation of structures and properties of nucleic acids has fascinated and
challenged researchers ever since the discovery of their relation to genes. Extensive
studies have been carried out on these species to unravel the mystery behind the
selection of these molecules as genetic material by nature and to explain various
physico-chemical properties. However, a vast pool of information is yet to be
discovered. DNA constituents, mainly aromatic purine and pyrimidine bases, absorb
ultraviolet irradiation efficiently, but the absorbed energy is quickly released in the
form of ultrafast nonradiative decays. Recently impressive progress has been made
towards the understanding of photophysical and photochemical properties of DNA
fragments.
