• 中文摘要： Normal coordinate analysis of Xn type molecules can be carried out in the Cartesian space as well as in the internal space. Force constants in Cartesian Coordinates for aromatic compounds belonging to Dn.. group are calculated. The force constants of benzene are evaluated from vibrational frequencies both in the ground state and the 1Bru excited state.
  The calculated frequencies of planar carbon vibration of annulene of any N are tabulated. The normal coordinates derived from the calculation of 10-annulene are roughly the same of naphthalene derived more elaborated by Scherer. The normal nodes in 10-annulene are indeed good approximations to the ones in naphthalene. This conclusion is valid for the other aromatic compounds.
