Web0cis-stilbene minimum). From here, trajectory basis functions (TBFs) can either proceed along the isomerisation coordinate, towards the trans-stilbene product, or along the cyclisation coordinate, towards the DHP product. Although CASSCF finds DHP-like and cis-stilbene-like minima on S 1, we could not locate these with CASPT2. It is unclear at this Web5.2 Stilbenes. Both trans - and cis -stilbene are stable molecules with the conformation of the trans form slightly lower in energy by about 4.6 kcal/mol and with the barrier to …
