CCL:G: fukuifunction



Hi,
I am working  on a molecule to calculate local fukui function but with some methods (MPA,NPA,HPA) the values be negative and I can't compare the reactivity of the nucleophilicity or electrophilicity of atomes in molecule. I have seen some articles that calculated the frontier molecular density that HOMO and LUMU is like f(+) and f(-) with positve values. Could you tell me what keyword to use the calculation molecular density in G03 I tried with keyeord :pop but  the gaussian does't work? and How can find them in the output results.
I express my thanks for your time and generous help.
Sincerely yours
M.Haghdadi
