A quote
From R. Ernst, G. Bodenhausen and A. Wokaun "Principles of NMR in one and
two dimensions" Claredon Press 1987, p.3
"spectroscopy stands in close analogy to techniques which measure
the transfer function of an electronic device. (...) It is well known that
the transfer function completely characterizes a linear
time-independent system. Many of the concepts of spectroscopy
stems from the consideration of linearly or approximately linear
systems for which a simple and elegant mathematical treatement is
possible. (...) It has been known for many years that the free
induction decay is equivalent to the impulse response for linear
systems."
