"Optical spectra of polyalanine in the W(nπ*) and NV1(ππ*) bands are calculated using the time-dependent Hartree-Fock technique and the INDO/S Hamiltonian. Examination of the transition density matrices shows that excitations in the NV1 band involve significant charge transfer between nearest and third-nearest neighbor amide groups. Our analysis suggests that the Frenkel exciton Hamiltonian cannot adequately describe the electronic excitations in the NV1 band."^^ . "2001-01-01" . . "3" . "14" . .
