The results are discussed and qualitatively interpreted in terms of the forced electric dipole and dynamic coupling mechanisms of the 4f-4f intensities, thus indicating that the forced electric dipole mechanism is dominant.487-493engAmino acidsNeodymiumTransition intensity parametersArtigo10.1590/S0103-50531998000500014S0103-50531998000500014WOS:000077494800013Acesso aberto2-s2.0-00322738362-s2.0-0032273836.pdf
