The absorption spectrum of a molecular compound in the microwave radiation range provides information about the: 1.Electronic structure of the molecule 2. Bonds and bond energies of the molecule 3. Shape of the molecule

2. Bonds and bond energies of the molecule

Explanation:

The absorption spectrum is an electromagnetic spectrum which is used for observing the intensity of the radiations which have been absorbed by the substances shown by the pattern of dark lines or bands. Infrared and microwave spectroscopy are specialized techniques which are used for observing the bonds and bond energy of the molecules which can be observed by measuring the frequencies at which the radiations are absorbed.
