Number of accessible atoms for electronic state
There is a possibility to calculate number of accessible atoms for each electronic state. See James P. Lewis et.al, Phys.Chem.B 2003,2581-2587 http://pubs.acs.org/doi/abs/10.1021/jp026772u.
input files
To write out number of accessible atoms for electronic states keyword iwrtpop must be set equal to 1 in fireball.in inside &OUTPUT. fireball.in file should look like:
&OPTION
basisfile = answer.bas nstepf = 1 icluster = 1 ifixcharge = 1 dt = 1 &END &OUTPUT iwrtpop = 1 &END
The range of states for wich number of accessible atoms is calculated can be limited. To limit range we use pop.optional, which has 2 rows: lower energy range and upper energy range.
5 -5
output file
Output is printed inside populations.dat file. Example of populations.dat file is shown below.
