CCL:G: [CCL] Nature of the lowest triplet state



Dear all,
 
I am an experimentalist by training and novice to the quantum chemical calculation. However, in  order to corroborate the experimental findings, I would like to predict the nature(pi-pi* or n-pi*) of the lowest triplet state(T1) in wide varieties of solvents using Gaussian 09.
 
I will be grateful for any kind of suggetions on this.
 
Thanks in advance......
 
regards
Rishi
