Is it normal for Gaussian to give negative frequencies? I used
the DFT B3LYP 6-31G* (d,p) basis set to calculate the
Vibrational frequencies and one is negative. I also used HF
6-31G and got a negative one as well for the first mode.

It is normal -- BUT negative frequencies mean something very
specific in Gaussian. We will have class in the computer lab on
Friday to discuss this. <br>
