Question

The fundamental and 1st overtone of a molecule are found 2886 (1/cm) and 5668 (1/cm). Calculate equilibrium oscillation wave no. and the anharmonicity constant

Answer 1

To determine the equilibrium frequency and the constant of anharmonicity, it is necessary to

obtain at least two wave transition numbers. The vibrations in diatomic molecule can be treated in

a similar way. Instead of the spring with force constant k, we have in the case of diatomic

molecules binding of the two nuclei through a bond with a force constant k and these nuclei

oscillate with a zt:aracteristic oscillational frequency.
