CHAPTER 26. LINEAR AND NON-LINEAR RESPONSE FUNCTIONS, RESPONSE286<br />

.GSLEGN Use a Gauss–Legendre grid for calculating imaginary polarizabilities.<br />

.MAX IT<br />

READ (LUCMD,*) MAXITC<br />

Maximum number of iterations for solving a linear response equation. Default is 60.<br />

.MAXITO<br />

READ (LUCMD,*) MAXITO<br />

Maximum number of iterations in the optimal orbital algorithm [22]. Default is 5.<br />

.MAXMOM<br />

READ (LUCMD,*) MAXMOM<br />

The maximum order of the Cauchy moments calculated. The default order is 6.<br />

.GRID<br />

READ (LUCMD,*) NGRID<br />

Read in the number of grid points to use in the numerical integration of the Cauchy<br />

moments. Default is 10.<br />

.QUADMOM Sets A and B to the quadrupole operators.<br />

.QUADXX/XY/XZ/YY/YZ/ZZ Sets A and B to the XX, XY, XZ, YY, YZ, or ZZ component<br />

of the quadrupole operator, respectively.<br />

.PRINT<br />

READ (LUCMD,*),IPRC6<br />

The line following gives the print level for the calculation of Cauchy moments.<br />

.PROPRT<br />

READ ’(A)’, LABEL<br />

Sets A and B to a given operator with label; LABEL. (The calculation of the operator<br />

must be specified to the integral module, see section 22.) This keyword may be<br />

repeated for different properties.<br />

.THCC6<br />

READ *, THCC6<br />

Relative convergence threshold for all requested linear response functions. Default<br />

is 1.0D-3; note that this number should be at least 10 times bigger than the final<br />

gradient norm in the SCF/MCSCF wave function optimization.¡<br />

Comments:<br />

You must tell the integral module to calculate the necessary one-electron integrals.<br />

For .C8SPH, .C8ATM, or .C8LMO you will need
