We determined the heat released in the condensing flow of a CH3 CH2 OD/ D2 O /carrier gas mixture (EtOD/ D2 O for brevity) through a supersonic Laval nozzle by integrating the equations for supersonic flow with condensation, using the static pressure, temperature, and mole fractions of EtOD and D2 O monomers [S. Tanimura, B. E. Wyslouzil, M. S. Zahniser, J. Chem. Phys. 127, 034305 (2007)] as inputs. by considering the depletion of the monomer species, the deviation of the pressure from the isentropic value, and the heat released, we estimated that ∼10% of the EtOD molecules are present as …
