Li2 excited triplet states |
Hello! I wrote some time ago about a problem in calculating the little
a state of Li2 using G92. My problem is cleared up; I only needed to have the
two atoms approach eachother "from ifinity" rather than move "toward infinity"
from a close distance. Thus ends the problem of the lowest electronic state
of triplet Li2.
Now, however, I am trying to calculate the first excited electronic
state of triplet Li2, which asymptotically separates into an s and a p atI have
tried to use Guess=alter to populate a Sg and a Pi orbital with two of
my alpha electrons (as there are 4 electrons in the alpha, I am assuming two are
the valence electrons). The G92 seems to understand that I want to switch the
electrons from Sg Sg and does generate a Sg and a Pi. BUT, then, it constantly
reverts back to Sg Sg and gives me the lowest electronic state! I used
guess =(alter, always) and this still occurs...
Any helpful hints would be much appreciated...
