Unformatted text preview: ) Diode-array spectrophotometers can detect the entire spectral range essentially
simultaneously and can produce a spectrum in less than a second. Conventional
instruments require several minutes to perform the same task. Consequently, diodearray spectrophotometers can be used to monitor processes that occur on very fast
time scales. 16. In a deuterium lamp, the input energy from the power source produces an excited D2
molecule that dissociates into two atoms in the ground state and a photon of radiation. As
the excited deuterium molecule relaxes, its quantized energy is distributed between the
energy of the photon and the kinetic energies of the two deuterium atoms. The l...
