The mass to use in the expression for the vibrational frequency of a diatomic molecule is the
Question:
The mass to use in the expression for the vibrational frequency of a diatomic molecule is the effective mass µ = mAmB/(mA + mB), where mA and mB are the masses of the individual atoms. The following data on the infrared absorption wavenumbers (in cm−1) of molecules are taken from Spectra of diatomic molecules, G. Herzberg, van Nostrand (1950):

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
