class ConfigurationInteractionReactionPathProblemCalculator

Bases: object

Class for performing full configuration interaction calculations on reactions.

__init__() None

Initialize instance of the full configuration interaction calculator for reaction path problems.

Return type:

None

calculate(reaction_path_problem: RestrictedReactionPathProblem | UnrestrictedReactionPathProblem) ReactionPathProblemCalculatorResult

Solve the configuration interaction (FCI or CASCI) calculation.

The FCI/CASCI energy is calculated for every geometry along the reaction path using the FCI/CASCI ground state problem calculator.

The Hamiltonian for all geometries are assumed to be real.

Parameters:

reaction_path_problem (RestrictedReactionPathProblem | UnrestrictedReactionPathProblem) – The reaction path problem to solve.

Return type:

ReactionPathProblemCalculatorResult
