We propose to use MARI to look at the full rotational spectrum of H2 in Ni-MOF-74 obtaining the full momentum distribution for H2 only at the Ni metal site and one with partial occupancy of the 2nd strongest site, with multiple incident energies. The momentum transfer for H2 is dominated, due to its light mass, by the zero-point motion. We can therefore access information about the binding of H2 in Ni-MOF-74 from both the rotational levels and the local interactions of H2 in relation to the framework. The advantage of using MARI for such a study is the ability to distinguish the low energy (<20 meV) rotational transitions, such as the J = 0 to J = 1 in Mg-MOF-74, however the higher order J = 1 to J = 2, transitions are also clearly discernable and as such one can determine the relationship between the amount of o-H2 vs. p-H2 in adsorbed in Ni-MOF-74 as a function of the amount of n-H2.
