A normal coordinate analysis on flucytosine has been carried out with a systematic set of symmetry coordinates following Wilson’s F-G matrix method. The potential constants evaluated for the molecule are found to be in good agreement with literature values thereby confirming the vibrational assignments. To check whether the chosen set of vibrational frequencies contributes maximum to the potential energy associated with the normal coordinates of the molecule, the potential energy distribution has been evaluated.
