Any quantum mechanical software (e.g., Gaussian03) can compute the fundamental frequencies (3N-6) and force constant for each frequency..

I don't understand exactly about force constant..??

For a particular mode of vibration what does this force constant mean?

For a molecular with 2 atoms we can tell force constant is between two atoms..but for polyatomic molecules is there any good way to understand??

thanks
