    "abstract": "The multicanonical ansatz is used to study variations in the energy landscape\nof a small peptide, Met-enkephalin, under a change from the ECEPP/2 force field\nto ECEPP/3. Local minima with energies up to 5 kcal/mol higher than the global\nminima are sampled and classified according to H-bridges and backbone angles.\nThe distribution and relative weight for various temperatures of the minima are\ncalculated and compared for the two force fields. We demonstrate that while\nthere are small differences in the energy landscape our results at relevant\ntemperatures are robust under changes between ECEPP/2 to ECEPP/3.",
