WebIn neutron diffraction experiments on crystalline cytosine monohydrate, 3 the HNCN out-of-plane angle was determined to be 3.4°, and a slight puckering of the ring was observed. Including hydrogen bonding moieties in the optimization calculations (four water molecules surrounding the N1 radical of cytosine) lowered the amino group puckering to ... WebThe crystal structure of both guanine hydrochloride monohydrate and guanine hydrochloride dihydrate is monoclinic, with four molecules in the unit cell (9, 10). For these two host crystals the orthogonal a*,b,c reference system has been used for the EPR measurements and analysis.
