Hi Piotr,

This should be solved in G16 as they moved the default for Acc2E to 12.

Hi Piotr,

This problem has been reported a few times. The most common suggestion being to add any of these options to the frequency job to force the in-RAM algorithm (far more efficient apparently):

Int=Acc2E=11
or
CPHF(MaxInv=10000)

Hope it works for you.

Best,
Carlos

Hi everybody,
I'm seeking your help with Gaussian calculations of analytical frequencies for a structure that I have optimized (opt=tight) at wb97xd/def2tzvpp. Subsequent job with freq=noraman (otherwise everything from the checkpoint file) failed to converge although it is quite close to the convergence limit (actually oscillated last couple of hundreds passes): 

1 vectors produced by pass999 Test12= 3.84D-13 1.00D-09 XBig12= 1.00D-14 1.13D-09.
1 vectors produced by pass*** Test12= 3.84D-13 1.00D-09 XBig12= 9.78D-15 1.41D-09.
CPHF failed to converge in LinEq2.
Error termination via Lnk1e 

I have rwf and chk files. My question is if there a way to extract frequencies from the current data (by either lifting slightly the criteria or other ways)? If you know options, IOPs, or anything that would allow me to get the frequencies I would appreciate greatly the info.
Cheers,
Piotr Paneth

Below is an example of generating such cube file for water: Write a plain text file named "water.chg" with below content O -1.68940800 0.00002500 0.00194100 -0.728713 H -1.08142400 -0.01012400 -0.78063300 0.364427 H -1.06246900 0.00994900 0.76945700 0.364286 The 2,3,4 columns correspond to XYZ coordinates in Angstrom, and the last column corresponds to atomic charges. Then boot up Multiwfn and input water.chg 5 // Generate grid data 8 // ESP based on atomic charges 2 // Medium quality grid Then you can use option -1 to visualize isosurface of the grid data, or use option 2 to export the grid data to .cub file. -------------------------------- Best regards, Dr. Tian Lu Beijing Kein Research Center for Natural Sciences, Beijing, P.
