Question

Describe why molecules such as N2O or CH4 can be detected with spectroscopy method.

Give one limitation of spectroscopy in determining the composition of a planets atmosphere.

Answer 1

It is depicts the transitions of a system from one quantum state to another.
It is due to absorption or emission of electromagnetic radiation.
These rules have been inferred for electromagnetic transitions in particles, in molecules, in nuclear and so on.
It may indicated by the to the strategy used to observe the transition.
spectroscopy deals with rotaton energy levels and is only applicable to molecules with permenant dipole moment. vertical component of dipole moment vector should change sinusoidally with time such that it can interact with incident radiation.only polar molecule obeys these condition.
