ShareNew method to measure ratio of ortho- and parahydrogen.
Author(s) : WANNER M., HOFMANN A.
Type of article: Article
Summary
The new method makes use of the caloric differences of the two hydrogen modifications. Parahydrogen has a slightly lower enthalpy than orthohydrogen and the enthalpy of an ortho-para hydrogen mixture is directly proportional to the ortho-para ratio.
