The H 2 ligand in 1 is stabilized only by nitrogen ligands . 1 H‐Detecting 2D‐( 1 H, 103 Rh)‐NMR spectroscopy, an NMR procedure in the preliminary phase of which a heteronuclear two‐spin coherence is excited, together with variation of the 1 H‐transmitter frequency, made it possible to read directly from the spectrum both the chemical shift of the metal and the number of hydride ligands present.
