Problem
An analytical instrument is designed to monitor both the stretching vibrations of functional groups and electronic excitations in organic pigments during a single experiment. Which combination of radiation sources would best meet this requirement?
(a) Ultraviolet for vibrations and infrared for electronic excitations
(b) Infrared for vibrations and ultraviolet/visible for electronic excitations
(c) Microwave for vibrations and near-infrared for electronic excitations
(d) Far-infrared for vibrations and visible light for electronic excitations
