Hi all I posted a question at the NWChem forum (http://www.nwchem-sw.org/index.php/Special:AWCforum/st/id644/Do_I_have_an_imaginary_frequency....html), and they suggested I get in touch with the Avogadro developers.
In a B3LYP/cc-pvtz frequency calculation, the log file lists: ---------------------------------------------------------------------------- Normal Eigenvalue || Projected Derivative Dipole Moments (debye/angs) Mode [cm**-1] || [d/dqX] [d/dqY] [d/dqZ] ------ ---------- || ------------------ ------------------ ----------------- 1 -32.993 || 0.001 0.000 -0.009 2 0.000 || -0.001 0.002 0.012 3 0.000 || 0.000 -0.023 0.001 4 0.000 || 0.000 0.009 0.001 5 0.000 || -0.001 -0.003 0.017 6 0.000 || 0.000 0.011 0.001 7 0.000 || 0.006 0.000 -0.074 8 56.848 || 0.000 0.000 0.000 9 77.476 || -0.030 -0.001 0.393 10 116.618 || -0.244 -0.001 -0.019 11 154.375 || 0.000 0.000 0.000 12 250.918 || -0.001 0.387 0.002 When I try to visualize the file in Avogadro, it does not show me this -32.99 cm-1 imaginary vibration. Is this expected behavior? Thanks and regards. -- Andrew Yeung Donald J.
