  A quantum framework, according quantum theories of electromagnetic
(EM)radiation to matter response, leads to a handy scheme addressed to examine
both physical and chemical processes. Fundamental quantum effects such
asentanglement, coherence, de-coherence and re-coherence yield a fully quantum
physical presentation applicable to chemical processes. A photonic basis-set
obtains including all possibilities accessible to a system in abstract space;
electronuclear (EN) base states put in resonance by photon fields are the
ground where quantum states, q-states, would show time evolution. At laboratory
space where energy and angular momentum conservation hold quantum dynamics
(i.e. amplitude changes) is to be driven by low frequency EM radiation, e.g.
microwaves. Materiality sustaining q-states unchanged.Here, focus on
construction and reading of photonic quantum states that underlie a host of
physical processes recently submitted to experimental examination. The approach
moves away interpretational issues using classical physics language to focus on
apprehending quantum states including experimental information.
