This is essentially the idea of the Partial Hessian Vibrational Analysis (PHVA) approach.

I have defined this in the input (also attached as file), and for a full vibrational analysis (i.e. no constraints) this works without problems. I always obtain this file. For various reasons, it would be very useful to output this file in any case. Could this be looked into by someone. </div><div><br></div><div>Thanks for your comments</div><div><br></div><div><br></div><div>Tobias</div><div><br><div><br></div><div><p style="font-size:11px;line-height:normal;font-family:Menlo;background-color:rgb(255,246,220)"><span>&MOLDEN_VIB</span></p>
