[ADF-LIST] Hybrid XC B3LYP not supported by analytical frequencies

Dear Pr. Lotfi Belkhiri,

To implement analytical frequencies with hybrid functionals is on the 
wish list (TODO list) for ADF. However, this is a far from trivial task.
It should be possible to display numerical frequencies with ADF. If you 
find problems could you send an input and output of an example that 
gives such problems to support at scm.com ?

Best regards,
Erik van Lenthe
