Question

Which is more sharp vibrational rotaional and elecronics spectra?

Answer 1

Answer:

electronic Spectra is more sharp than vibrational rotational

hope it helps u

mark me brainliest,if u satisfy with it

Answer 2

Answer:

here is ur answer mate...

Centrosymmetric linear molecules have a dipole moment of zero, so do not show a pure rotation spectrum in the infrared or microwave regions. On the other hand, in certain vibrational excited states the molecules do have a dipole moment so that a ro-vibrational spectrum can be observed in the infrared
