This new, expanded edition provides a fresh, photon-based description of
modern molecular spectroscopy and photophysics, with applications that are
drawn from across the breadth of chemistry, biology, physics, and materials
science, including recent developments. The focus is on the mechanisms that
operate at the fundamental level, on how light absorption and scattering occur
in molecules, what happens to the energy which the molecules acquire, and what
may be learned from the study of these processes. Mathematics is again kept to
a minimum though quantitative understanding is nevertheless put into practice via
example calculations throughout the text. With the aid of extensive, purposely
devised illustrations, this approach fosters a deeper intuition for the
photophysical processes involved in light-matter interaction, aiming to
consolidate the principles and to exemplify how widely ranging information can
be derived from spectroscopic studies.
