What is the importance of the 2 Allotropes of Hydrogen O-Hydrogen and P-Hydrogen?

THese are not allotropes of hydrogen. These are spin-isomers of hydrogen. Molecular hydrogen occurs in two isomeric forms, namely with its two proton spins aligned either parallel (orthohydrogen) or antiparallel (parahydrogen). In the state of thermal equilibrium at room temperature dihydrogen contains 25 % of parahydrogen (nuclear singlet state) and 75 % of orthoghydrogen (nuclear triplet state).
