Neste trabalho foram obtidos os espectros de RMN CPMAS de fósforo-31 e carbono-13 do imino(trifenil)fosforano e do brometo de amino(trifenil)fosfônio. A análise detalhada desses espec-tros forneceu informações sobre o tensor de blindagem de 31P e o tensor de acoplamento quadrupolar de 14N. O espectro estático de 31P do brometo foi também analisado em termos dos tensores relevantes. Os cálculos ab initio no nível hf/6-31g * reproduzem bem os dados observados, com exceção dos deslocamentos isotrópicos, os quais requerem cálculos com bases maiores e/ou de um nível teórico superior. As orientações dos tensores na estrutura do brometo foram derivadas através dos cálculos. Phosphorus-31 and carbon-13 CPMAS NMR spectra have been obtained for imino...
