Consider the following statements as they apply to radiation sources and atomic spectroscopy. Decide if each is true or false. False A hollow cathode lamp is used as an AAS source because its emission lines are very broad. True Gaseous cations dislodge metal atoms from the cathode surface in a hollow cathode lamp in a process called sputtering. True Neutral Ca atoms, singly charged Ca ions, and doubly charged Ca ions each have their own characteristic emission energies. True Photons transmitted through the sample are detected in AES. True Room lights contribute significantly to the background noise in AAS.

Electronic Transitions and Spectroscopy

The term “electronic” connotes electron, and the term “transition” implies transformation. In a molecule, the electrons move from a lower to a higher energy state due to excitation. The two energy states, the ground state and the excited state are the lowest and the highest energy states, respectively. An energy change is observed with this transition, which depicts the various data related to the molecule.

Photoelectron Spectroscopy

Photoelectron spectroscopy (PES) is a part of experimental chemistry. It is a technique used in laboratories that involves projecting intense beams of radiation on a sample element. In response, the element ejects electrons for which the relative energies are measured.
