Hi All,
I am trying to calculate first 12 roots of b3 irrep in D2 group using "symmetry" and "targetsym" keywords in the tddft block. Any combination of these two keywords, as well as using them separately, always produces roots in all four representations of this group. What am I missing? Thanks in advance!
Maria
Here is my input:
echo
title "ch4-Tdsym test"
geometry units angstroms print
H -0.629312 0.629312 0.629312
C 0.000000 0.000000 0.000000
H 0.629312 -0.629312 0.629312
H 0.629312 0.629312 -0.629312
H -0.629312 -0.629312 -0.629312

end
