NAME

     cints − One‐ and Two‐Electron (Derivative) Integrals Program

DESCRIPTION

     The  program  cints  computes (derivative) integrals of some
     one‐ and two‐electron  operators  which  appear  in  quantum
     chemical theories over symmetry‐adapted cartesian and spher‐
     ical harmonics Gaussian functions.

     input.dat                Input                          file
     FILE30                   Checkpoint file FILE31

     Input for this program is  read  from  the  file  input.dat.
     Most of the keywords are not necessary for routine task. The
     following keywords are valid:

     PRINT = integer
          Determines   amount   of  information  to  be  printed.
          Defaults to 0.

     CUTOFF = integral
          The negative of the exponent of the cutoff  imposed  on
          two‐electron integrals.  Default is 15 which results in
          two‐electron  integrals of greater than 1e‐15 magnitude
          to be stored in FILE33.

     S_FILE = integer
          The file number to store overlap integrals. Defaults to
          35.

     T_FILE = integer
          The file number  to  store  kinetic  energy  integrals.
          Defaults to 35.

     V_FILE = integer
          The  file number to store nuclear attraction integrals.
          Defaults to 35.

     ERI_FILE = integer
          The file number to store electron repulsion  integrals.
          Defaults to 33.
