Manipulating stereoselectivity of parahydrogen addition to acetylene to unravel interconversion of ethylene nuclear spin isomers

“…14 This approach can be extended to study reaction product distributions and the operation of model catalytic reactors. 15 Moreover, the nuclear spin isomerism phenomenon and relative NSIM ratios are exploited for spin temperature measurements in interstellar media, protostars, and other space objects. [16][17][18][19] It is often assumed that under conditions of interstellar space, the ortho-para ratio of small symmetric molecules practically does not change over time since a space object was formed, which allows conclusions to be drawn about the conditions of its formation.…”
