Second-order polarization propagator approximation: *SOPPA

This input module controls the calculation of molecular properties using the second-order polarization propagator approximation, see Chapter 18.

.HIRPA
Use the higher-order RPA Polarization Propagator Approximation.

.SOPW4
Requests that the W4 term in the SOPPA expressions are calculated explicitly.
