Planetary nebulae show a wide range of elemental abundances. Molecular line observations of planetary nebulae in the (sub-)mm band provide a unique opportunity to test existing chemical codes that have been designed to predict molecular abundances. Observations of 13C-bearing molecules in planetary nebulae in the (sub-)mm band are a cost effective means to determine the 12C/13C isotopic ratio in planetary nebulae, hence to constrain stellar evolution models.
