 Dear netters:
    I am interested in the calculation of the vibrational frequency of
 cation radical by AM1, HF and DFT. sometimes ago, there are many discussion
 about the calculation of the vibration frequency for neutral molecule,
 could you give me any suggestion about the cation radical?
    Thank in advances,
