That is because it picked up the SCF movecs file as ESP doesn't recognize the mp2nos file by default. try the following input deck.

Notes:

1. I set start so I know the prefix for the output files, i.e. h2o.movecs and h2o.mp2nos

2. I set 'set "esp:input vectors" h2o.mp2nos ' to tell the esp module to use h2o.mp2nos as the vectors file for its calculations.

[QUOTE= Jan 24th 1:06 pm]Did not work. With "task MP2 gradient" and "task scf energy" the result is the same.

Try "task mp2 gradient".
