Subject: G98W & Hessian units

Hi there --

Can someone tell me exactly what units the Hessian matrix given by
Gaussian98 output is in?
And what exactly I have to do (what constants, expressions, etc.) to
obtain the frequencies?

Right now, I can get the frequencies out by multiplying the
sqrt(eigenvalues(Hessian)) by ~1450, but for the life of me, I can't
figure out what collection of constants will produce this.

Thanks in advance.

Connie
