Ahumada, H.; Montecinos, R.; Martínez, R.; Araya Maturana, Ramiro; Weiss López, Boris (SOCIEDAD CHILENA DE QUIMICA, 2004-09)Deuterium quadrupole splittings, of deuterated water, Deltav, in anionic discotic nematic lyomesophases are always much larger than in cationic mesophases. To explore the possible origins of this difference, Deltav and T-1 ...
