Differentiate between atomic and molecular spectrum ?
Atomic spectrum refers to the spectra produced by atoms, typically having sharp lines at specific wavelengths. This spectrum is generated when atoms emit or absorb electromagnetic radiation, and the lines represent transitions between different energy levels within the atom.
On the other hand, molecular spectrum refers to the spectra produced by molecules, which typically consist of bands rather than sharp lines. This spectrum is produced when molecules absorb or emit electromagnetic radiation, and the bands represent vibrational, rotational, and electronic transitions within the molecule. Molecular spectrum is more complex than atomic spectrum due to the multiple degrees of freedom available to the molecules.
