RESUMO
Thermodynamic constants (Cv> Cp and itf) and physical properties a, fis and v) of the n-CnF2n+2 compounds with n=4 to 8 were evaluted and estimated from correlations. The values are compared with those obtained for the corresponding molecules in the n-CnH2n+2 series and tfje results were found to be consistent with the published experimental data. The liquid structure or n-perfluorated compounds is discussed on the basis of these data.

RESUMO
The infrared spectra of the complexes[ Co (NH3)5 X ] X2 (X = Cl, Br) with H/D isotopic substitution have been recorded in the regions of low energy. The assignment of the vibrational metal-ligand modes have been discussed and the force constants for the framework of these complexes vere calculated using different procedures of calculus.
Os espectros infravermelhos dos complexos [ Co (NH3)5 X ] X2 (X = Cl, Br) com substituição isotópica H/D, têm sido registrados nas regiões de baixa energia. Discute-se a atribuição vibracional dos modos metal-ligante e determinam-se por diferentes procedimentos de cálculo as constantes de força do esqueleto dos complexos.

RESUMO
Using projection operators and based on the C3v local symmetry of isolated M-XY3 groups, internal symmetry coordinates are obtained for the MfXYjJ
Mediante a utilização dos operadores de projeção e baseados na simetria local Cjv dos grupos M-XY3 isolados, obtém-se as coordenadas de simetria internas para o modelo molecular M(XY3)5Z de simetria C4v
