The infrared absorbtion of the N-H stretch in amines occurs approximately at a wavelength of 2.9 x 106 m. What is the approximate vibrational force constant, k, of N-H bond? Note: you can assume the reduced mass is equal to the mass of the H atom which is reasonable since it's attached to a much heavier atom). O 48.0 kg/s2 1.20 x 102 kg/s² O 7.0 x 102 kg/s² 4.2 x 101 kg/s? O 1.3 x 103 kg/s²
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.
