CCL:G: Magnitude of static field used for calculation of polarizability



Dear Dr. Lehtola,

Can You please suggest something good to read about the theory of CPHF and response functions? I have performed some literature search but it was quite hard to me to sum it up to get at least some understanding of "how it works": I have never attended any serious course on quantum mechanics or chemistry, and I didn't find much literature for laymen like me either. Most books I have read contain either the essential basics or deep discussion, being quite sparse in between.

With deep gratitude,
Igors Mihailovs

Dear Suresh,

By default, Gaussian uses CPHF for polarizabilities (quite different from the response formalism, as far as I can judge – /can anyone comment on that?/)
CPHF *is* linear response.
