Consider the rotational spectrum of a molecule XY. If the first line in this spectrum is observed at 3.84235 cm", calculate the internuclear distance In nm for the molecule XY. If the masses of X and Y are 19.92168 kg and 26.56136 kg respectively. 0.2761 mm 0.1356 nm 0.6953 nm 0.1131 nm
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.
