The work characterizes the electric dipole moment and the infrared spectrum of the molecule C13H20BeLi2SeSi. Calculations obtained in the ab initio RHF (Restrict Hartree-Fock) method, on the set of basis used indicate that the simulated molecule C13H20BeLi2SeSi features the structure polar-apolar-polar predominant. The set of basis used that have are CC-pVTZ and 6-311G** (3df, 3pd). In the CC-pVTZ base set, the charge density in relation to 6-311G** (3df, 3pd) is 50% lower. The length of the molecule C13H20BeLi2SeSi is of 15.799Å. The magnitude of the electric dipole moment |p| total obtained was p = 4.9771 Debye and p = 4.7936 Debye, perpendicular to the main axis of the molecule, for sets basis CC-pVTZ and 6-311**(3df,3pd), respectively. The infrared spectra for absorbance and transmittance and their wavenumber (cm-1) were obtained in the set of bases used. The infrared spectrum for Standard CC-pVTZ shows peaks in transmittance with Intensity (I), at wavenumber 1,125.44 cm-1, 1,940.70 cm-1, 2,094.82 cm-1, 2,178.43 cm-1, 2,613.99 cm-1 and transmittance 433.399 km/mol, 399.425 km/mol, 361.825 km/mol, 378.993 km/mol, 433.774 km/mol, respectively. While the infrared spectrum for Standard 6-311G**(3df, 3pd), shows peaks in transmittance, at wavelengths 1,114.83 cm-1, 1,936.81 cm-1, 2,081.49 cm-1, 2,163.23 cm-1, 2,595.24 cm-1 and transmittance 434.556 km/mol, 394.430 km/mol, 345.287 km/mol, 375.381 km/mol, 409.232 km/mol, respectively. It presents “fingerprint” between the intervals (680 cm-1 and 1,500 cm-1) and (3,250 cm-1 and 3,500 cm-1). The dipole moments CC-pTZV are 3.69% bigger than 6-311G** (3df, 3pd). As the bio-inorganic molecule C13H20BeLi2SeSi is the basis for a new creation of a bio-membrane, later calculations that challenge the current concepts of biomembrane should advance to such a purpose.
