# EOM_GUESS

> Specifies a set of single-excitation guess vectors for the EOM-CC procedure. If EOM_GUESS = `SINGLES`, the guess will be taken from the singles-singles block of the similarity-transformed Hamiltonian, Hbar. If EOM_GUESS = `DISK`, guess vectors from a previous computation will be read from disk. If EOM_GUESS = `INPUT`, guess vectors will be specified in user input. The latter method is not currently available.
