The geometric parameters and theoretical vibrational frequencies of 2-methyl-1- phenylpropan-2-amine calculated using Hartree-Fock method and Density functional theory (B3LYP) methods with 6-31G(d,p) basis sets. The scaled wave numbers are compared with the experimental values. The FT-IR and FT-Raman spectra were recorded in the region of 4000–400 cm-1 and 4000 –100 cm-1 respectively. Stability of the molecule arising from hyper-conjugative interactions, charge delocalization has been analyzed using Natural Bond Orbital (NBO) analysis. Mulliken analysis and thermodynamic parameters like entropy, Zero-point Vibrational energy, Specific heat, Rotational constant and Dipole moment have been calculated for the title molecule were performed by HF and DFT method.
