How to draw a line spectrum of a doublet of doublets of triplets (1:2:1) of doublets? Context: This is for one of the isomers of
[RhH(CO)(PR3)3] (only considering Rh, H, PR3 ligands).

I have attached an image of my attempt to draw a doublet of doublets of triplets, but unsure how to get in the final doublets.

Please can I have some tips on the best ways to draw these and what the final spectrum should look like.
