All publications resulting from use of this program must acknowledge Ref.  (calculations of singlet states) and  (calculations of triplet states and properties).
The command LT-DF-LCC2 calls the Laplace transformed LCC2 program, and LT-DF-LADC(2) calls LADC(2). The excited states of interest should be specified on the EOM card.
