| Mar 16, 2017 at 16:25 | comment | added | porphyrin | @ Ivan Neretin ; yes nuclear spin seems to be is the cause, D has a spin of 1 whereas H has spin 1/2. In $\ce{H2}$ the ortho-para ratio is 3:1 but 2:1 in $\ce{D2}$ there is some detail here chemistry.stackexchange.com/questions/67316/… which you will have to modify for deuterium. | |
