lennard jones parameters

[Nourissa]

Hi all
I have a question regarding lennard jones parameters in RASPA. What are the units used? And if my energy parameter is in Kj/mol how can I convert it to the used unit in Raspa

Input units for the Lennard-Jones are epsilon/k_B in units of Kelvin, and sigma in units of Angstrom (see manual, also for units and unit conversions).
