		                        Hi there: 
 
I am new to NWChem and I would like to run some calculations for open shell systems. How can I  set the multiplicity options in the input file for this sort of calculations? 
 
Here is a sample of my input file for a closed shell system. 
 
 ==============================
start 
 
memory 700 MB noverify 
 
echo 
 
geometry units angstrom noautosym 
He 0.0 0.0 0.0 
 
end 
 
basis "ao basis" spherical 
* library cc-pvdz 
 
end 
 
dft 
xc b3lyp 
grid fine 
odft 
convergence energy 1d-6 
iterations 150 
 
end 
 
 
set dft:frac t 
set dft:nfrac 1 
set dft:fnumall 1.000 
set dft:nfracb 1 
set dft:fnumallb 1.000 
 
 
set dft:rpa t 
 
task dft 
 ======================
 
your prompt help would be greatly appreciated. 
 
Thanks!
