Finding force constants for C2v molecules on Hondo

 I'm working on 5 atom molecules that are C2v, of the type MX2Y2 like
 CH2F2 on Hondo v8.2. My problem is that I'm not getting full resonable
 force constants. To save on band width, I won't go into full detail here,
 but if you think you can help me, please email me, and I'll send a full
 description of the problem and what I have done.
 Thanks in advance,
