Subject with nitrogen donor atom

The hydrogen-bonding abilities of the ring nitrogen atom have also been the subject of investigation using IR spectroscopy, with proton donors such as phenol, pyrrole, and acetylenes in dilute carbon tetrachloride solution. Good correlations are observed 128-131 thus Eq. [Pg.21]

The analysis of these data reveals the electronic parameters of the main regions of the uracil skeleton that change with biological activity. These are (1) the electronic parameters characterizing the hydrogen atoms at the heterocyclic nitrogens, and (2) the characteristics of atoms C5 and Cs and the double bond Cs = C(, which are subject to the influence of donor and... [Pg.453]
