Sketch the H NMR spectra for all of the isomers of RhH2Cl(PPh3)3. Consider only the hydride hydrogens (directly bonded to rhodium). Assume the following coupling constants: 1J(1H-103Rh)=300 Hz; 2J(2H-31P(cis))=30 Hz, 2J(1H-31P(trans))=120 Hz; 2J(1H-1H)= 10 Hz
Assume that the chemical shifts for chemically different environments are well seprated (no overlap signals). However, accurate chemical shift values do not need to be reported.
