In order to illustrate the reliability of our procedure, we use it to generate starting pathways for nudged elastic band calculations. Compared to cartesian space interpolation, our Z-matrix formulation holds significant advantages. A comparison is also provided to refined pathways making use of the Image-Dependent Pair Potential (IDPP) method. The Z-matrix results, even without any type of post-processing, are still competitive and offer clear advantages for conversion processes in molecular dimers. This is all carried out without any previous knowledge of the chemical step in question or manual user input.
