CCRESPONSE

Performs coupled cluster response property computations.

General

ABCD

  • Type: string
  • Default: NEW

ANALYZE

Do ?

CACHELEVEL

Cacheing level for libdpd

  • Type: integer
  • Default: 2

DIIS

Do use DIIS extrapolation to accelerate convergence?

GAUGE

Specifies the choice of representation of the electric dipole operator. Acceptable values are LENGTH for the usual length-gauge representation, VELOCITY for the modified velocity-gauge representation in which the static-limit optical rotation tensor is subtracted from the frequency- dependent tensor, or BOTH. Note that, for optical rotation calculations, only the choices of VELOCITY or BOTH will yield origin-independent results.

  • Type: string
  • Possible Values: LENGTH, VELOCITY, BOTH
  • Default: LENGTH

LINEAR

Do Bartlett size-extensive linear model?

LOCAL

Do simulate local correlation?

LOCAL_CPHF_CUTOFF

  • Type: double
  • Default: 0.10

LOCAL_CUTOFF

  • Type: double
  • Default: 0.01

LOCAL_FILTER_SINGLES

Do ?

LOCAL_METHOD

  • Type: string
  • Default: WERNER

LOCAL_PAIRDEF

  • Type: string
  • Default: NONE

LOCAL_WEAKP

  • Type: string
  • Default: NONE

MAXITER

Maximum number of iterations to converge perturbed amplitude equations

  • Type: integer
  • Default: 50

NUM_AMPS_PRINT

  • Type: integer
  • Default: 5

OMEGA

Array that specifies the desired frequencies of the incident radiation field in CCLR calculations. If only one element is given, the units will be assumed to be atomic units. If more than one element is given, then the units must be specified as the final element of the array. Acceptable units are HZ, NM, EV, and AU.

  • Type: array
  • Default: No Default

PROPERTY

The response property desired. Acceptable values are POLARIZABILITY (default) for dipole-polarizabilities, ROTATION for specific rotations, ROA for Raman Optical Activity, and ALL for all of the above.

  • Type: string
  • Possible Values: POLARIZABILITY, ROTATION, ROA, ALL
  • Default: POLARIZABILITY

REFERENCE

Reference wavefunction type

  • Type: string
  • Default: RHF

RESTART

Do restart from on-disk amplitudes?

R_CONVERGENCE

Convergence criterion for wavefunction (change) in perturbed CC equations.

SEKINO

Do Sekino-Bartlett size-extensive model-III?

Expert

WFN

Wavefunction type

  • Type: string
  • Default: SCF
