前面的优化是正常的四个Yes结束,做频率分析中出现:
Full mass-weighted force constant matrix:
Low frequencies --- NaN NaN NaN NaN NaN NaN
Low frequencies --- NaN NaN NaN
Diagonal vibrational polarizability:
NaN NaN NaN
Harmonic frequencies (cm**-1), IR intensities (KM/Mole), Raman scattering
activities (A**4/AMU), depolarization ratios for plane and unpolarized
incident light, reduced masses (AMU), force constants (mDyne/A),
and normal coordinates:
1 2 3
A A A
Frequencies -- NaN NaN NaN
Red. masses -- NaN NaN NaN
Frc consts -- NaN NaN NaN
IR Inten -- NaN NaN NaN
中间的Matrix也都是NaN
最后得到的correction是这样的:
Zero-point correction= NaN (Hartree/Particle)
Thermal correction to Energy= 0.002833
Thermal correction to Enthalpy= 0.003777
Thermal correction to Gibbs Free Energy= -0.147324
Sum of electronic and zero-point Energies= NaN
Sum of electronic and thermal Energies= -1977.250562
Sum of electronic and thermal Enthalpies= -1977.249618
Sum of electronic and thermal Free Energies= -1977.400718
最后的报错信息:

不知道是何种原因导致?
