If you have already calculated the vibrational frequencies using Jaguar, copy your *freq.01.in file to a new input file.

1) To the new file, in the &gen section,
Change ifreq=1 to ifreq=-1 (note the negative sign!)
Add the line igonly=1

2) Open up Maestro (if you haven't done so already)

3) Under the Applications Tab, Select Jaguar, and then select Initial Guess Only

4) Click the "Read" tab at the bottom and read in your input file with "Geometry and settings" (the default).

Your molecule should now be displayed. The "Job" section at the bottom of the window should read something like b3lyp/6-311+g*, Initial Guess Only, Frequencies. The first entry is your method and basis set. The second and third entries show up if you made the two changes in 1). If not, go back to Step 1).

5) Click on the Properties Tab and make sure that Vibrational Frequencies is checked (with an X) and "Use available Hessian" is checked (red in colour).

6) Click Start. A green window pops up. Make sure that the "Incorporate" tab says " Replace existing entries" (it should by default).

7) Click Start in this green window. A job monitoring panel shows up. The job should take a few seconds. When it's done, close the monitoring panel.

8) Click the project tab in Maestro (looks like a Table). Your job should show up. Scroll all the way to the right and click on the "V".

9) Select the frequency you want to observe and make sure the animate button is checked (red in colour).


Alternate Method that might work better!

1) Copy your freq.vib file to a freq.01.vib file.

2) Read in your Jaguar freq.01.in file into Maestro.

3) Click the project tab in Maestro, make sure the current job (usually the last file you read in) is highlighted, and then under Table, select Import, and then Vibrational Modes.

4) Select the frequency you want to observe and make sure the animate button is checked (red in colour).
