An FT-Raman, FT-IR, and Quantum Chemical Investigation of Stanozolol and Oxandrolone
We have studied the Fourier Transform Infrared (FT-IR) and the Fourier transform Raman (FT-Raman) spectra of stanozolol and oxandrolone, and we have performed quantum chemical calculations based on the density functional theory (DFT) with a B3LYP/6-31G ...
