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 spherical harmonics Gaussian functions.

INPUT FORMAT
Input for this program is read from the file Most of the keywords are not neccessary 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.
