Calculate the wavenumbers of the two highest energy vibrational transitions for the ¹271³5C| molecule. [Note: m(¹271) = 126.9045 u, and m(³5CI) = 34.9688 u; the vibrational wavenumber (ỹ) is 384.3 cm³¹; the first order anharmonicity constant (X₂) is 0.0039.] Hint: For this anharmonic oscillator, the question asks for an estimate of the type G(v+1) - G(v) = AG₁+2 for AG1/2 and AG3/2-
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.
