WebDec 8, 2014 · I think in water and D2O the main factor is not Van Der Waals but rather hydrogen bonding. So the boiling point of D2O is higher than H2O not because of the London forces, but because of the difference in electronegativity between the hydrogen and the water, creating an electrostatic attraction.
WebNov 21, 2015 · Looking on the NIST fluid properties database I see that the specific heat capacity (i.e. the heat capacity per unit mass) of D2O is just 1.5% higher than the specific heat capacity of H2O. So at 298 K this makes the molar heat capacity of D2O (84.963 J/K/mol) an astonishing 12.7% higher than H2O (75.38 J/K/mol). WebApr 26, 2016 · Using two-dimensional infrared spectroscopy, we have found that the nuclear motions of heavy water, D2O, are qualitatively different than those of H2O. The nonlinear spectrum of liquid D2O reveals distinct O–D stretching resonances, in contrast to H2O. Furthermore, our data indicates that condensed-phase O–D vibrations have a different ...
WebD2O exhibits about 2600 times neutron-moderating ability compared to H2O. This has contributed to the revolution in nuclear power production as D2O provided an optimized source as a moderator in pressurized heavy water reactor (PHWR).
