DFT study:

- The DFT optimised geometries and computed free enthalpies of
various limonene derived alcohol-carboxylic acids and their different possible dimers formed by polycondensation, as well as a related lactone and its ring-opened products.

- The thermochemistry of the reaction of lactonisation of alcohol/carboxylic acid 6a.
- The thermochemistry of the ring-opening of lactone 4 by benzyl alcohol.
- The thermochemistry of the isodesmic reaction between lactone 4 and isopropylisopropanoate.
- The thermochemistry of the condensation (all combination possible) between bifunctional alcohol/carboxylic acid 6a and 6b, to yield a dimeric ester, as a model for polymerisation.

Protocol: rM06-2X/6-311++g(2d,p)/cpcm=ethylethanoate/T=298.15K or 453.15K
