The two dimensional infrared photon echo spectrum of Antamanide (-1Val-2Pro-3Pro-4Ala-5Phe-6Phe-7Pro-8Pro-9Phe-10Pro-) in chloroform is calculated using an explicit solvent MD simulation combined with a DFT map for the effective vibrational Hamiltonian. Evidence for a strong intramolecular hydrogen bonding network is found. Comparison with experimental absorption allows to identify the dominant conformation. Multidimensional spectroscopy reveals intramolecular couplings and gives information on its dynamics. A two color amide-I and amide-A cross peak is predicted and analyzed in term of local structure.
