For people who stumble across this thread, I'll note that for me, "task dft frequency" gives me an immediate error, while "task dft freq" seems to proceed as desired. I am using NWChem 6.8.1. Cheers!

Let's imagine you first run a geometry optimization with the following input file
start h2o

geometry
0 0. 0. 0.
...

task dft optimize


Then, you can perform a frequency calculation with the optimized geometry of the previous run (provided that you kept the h2o.db and h2o.movecs files) by using the following input file that uses the restart option


restart h2o

task dft frequency
