Choose the correct answers and give a short explanation. In microwave spectra: - the separation of 2 lines in the spectrum for HF is less than for DF - the rotation constant for the HF molecule is greater than for DF (D: deuterium) - the spectrum lines separate as the rotational number increases - energy levels approach as the rotational quantum number increases
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.
