Safety in the Handling of Cryogenic Fluids
Equilibrium between Orthohydrogen and Parahydrogen A property of hydrogen
that can influence a number of its other properties, such as specific heat and
thermal conductivity, is the existence of the two forms of hydrogen, orthohydrogen

Literature Survey of
Orthohydrogen and Parahydrogen Research
A survey of the technical literature pertaining to ortho hydrogen and parahydrogen is presented.

Handbook of Particle Physics
To decide between these possibilities, he suggested looking at experiments on
the scattering of neutrons by para- and orthohydrogen. The experiments showed
that the scattering cross section of orthohydrogen is much larger than that of ...

Fundamental Equations of State for Parahydrogen, Normal ...
All three equations of state have the same maximum pressure of 2000 MPa and temperature of 1000 K. The uncertainty in density is 0.04% in the region between 250 and 450 K at and pressures from 0.1-300 MPa.

An Introduction to Applied Statistical Thermodynamics
only the even or odd values of j are allowed, depending on whether the nuclear
spin eigenstates are antisymmetric (parahydrogen) or symmetric (orthohydrogen)
, respectively. Furthermore, the nuclear degeneracy of the symmetric states ...

Rocket Propulsion Elements
... orthohydrogen toparahydrogen is exothermicand results in excessive boiloff,
unless complete conversiontoparahydrogen isachieved during liquefaction.
Liquid hydrogen is manufactured from gaseous hydrogen by successive
compression, ...

Identification of Defects in Semiconductors
degeneracies of the nuclear spin states. At low temperatures, the conversion of
orthohydrogen to the lower energy para configuration requires a forbidden
nuclear spin flip and proceeds very slowly. The H2 stretching band in GaAs was ...

Environmental Solutions
In order to minimize the storage boil-off losses, the conversion rate of
orthohydrogen to para-hydrogen should be accelerated with a catalyst that
converts the hydrogen during the liquefaction process (Newton 1967a,b; Baker
and Shaner 1978; ...
Franklin J. Agardy, Nelson Leonard Nemerow, 2005
Unfortunately, ordinary hydrogen is a mixture of para- hydrogen, in which the two
protons are set with their spins * R. Frisch and O. Stern, Z. Phys. 85, 4, 1933. I.

Life in the Universe: Expectations And Constraints
The vibrational and rotational motions are in quantum states resulting in two
different modifications of hydrogen: parahydrogen molecules that have antipar-
allel nuclear spins and even rotational quantum numbers, and orthohydrogen ...
