Description
The gas-phase photophysics of complex biomolecules enable us to understand the intrinsic structural and functional properties without solvent influence. The photodetachment and photodissociation of deprotonated 2’-deoxyadenosine-5’-monophosphate anion (dAMP–), a monomer of DNA, contribute to its intrinsic photoresponse, fragmentation channels, and the associated lifetimes. We report on the status of photodetachment and photodissociation measurements of dAMP– with UV laser light as a function of wavelength from 210 - 280 nm. The study is carried out by confining the anions generated from electrospray ionization, in a cryogenic 16-pole wire trap maintained at 2.9 K by buffer-gas collision.
