Re: CCL:question on TDDFT using Gaussian 03

Dear Ricardo,
 If you square these numbers, you get the '% contribution' of each of
 these one-electron transitions to the actual transition.
 In this case, you have:
 64% 22A-->26A
 37% 20B-->22B
 7%  21B-->23B
 If you know the nature of each of these orbitals, you can work out the
 nature of the overall transition, e.g. LMCT, MLCT, or even view it
 graphically (see gaussssum.sf.net), or send me an email.
