UV photoelectron and theoretical characterization of 2'-deoxyguanosine-5'-phosphate valence electronic properties: changes in structure associated with the B to Z-DNA conformational transition.

Abstract

He(I) UV photoelectron spectroscopy and ab initio SCF molecular orbital calculations with the 4-31G basis set have been employed to characterize the valence electronic structures of 2'-deoxyguanosine-5'-phosphate (5'-dGMP-). In 5'-dGMP-, the electron distributions of the upper occupied orbitals are localized and similar to those appearing in 1,9… (More)
