Marcus–Coltrin path

https://doi.org/10.1351/goldbook.M03701
A path @T06431@ over a @P04780@ which corresponds to the outermost vibrational turning points for the molecular species involved. This path was suggested as a device for calculating the @P04855@ of quantum-mechanical @T06531@: the trajectory for the system is considered to follow this path.
