Help me solve this chemystery problem

Do all of the THCa isomers share the same polymorphism?

THCa, A and B

There’s more than one isomer of THCa, and my buddy @onemadalchemist on IG was kind enough to dumb it down for me. [1520845864883] THC-A A or (6aR,10aR)-1-hydroxy-6,6,9-trimethyl-3-pentyl-6a,7,8,10a-tetrahydro-6h-benzo[c]chromene-2-carboxylic acid, is the top structure. THC-A B or (6aR,10aR)-1-hydroxy-6,6,9-trimethyl-3-pentyl-6a,7,8,10a-tetrahydro-6h-benzo[c]chromene-4-carboxylic acid, is the bottom structure. Now to find a way to separate them!
