Why Br2 microwave active?

I don't think it is. Microwave energy levels correspond to rotational modes, and for rotational spectroscopy, a molecule has to have a dipole moment... homonuclear diatomics like Br2 don't, and thus do not exhibit a pure rotational spectrum.


What are raman active molecule?

molecules without permanent dipole are called Raman active molecules


What is Raman Spectroscopy?

Raman Spectroscopy is a spectroscopic technique in condensed matter physics and chemistry. It studies vibrational, rotational & low-frequency modes in systems.


What meant by raman effect?

The Raman effect refers to the inelastic scattering of light by molecules, resulting in a change in energy of the scattered photons. This effect provides information about the vibrational and rotational modes of molecules, making it a useful tool for analyzing chemical structures and compositions. Raman spectroscopy is a common technique that utilizes the Raman effect for various applications in chemistry, physics, and materials science.


What is the mass of 4.89 x 1020 molecules of Br2?

1 mole Br2 = 159.808g Br2 = 6.022 x 1023 molecules Br2 4.89 x 1020 molecules Br2 x 1mol Br2/6.022 x 1023 molecules Br2 x 159.808g Br2/mol Br2 = 0.130g Br2


Are there different types of raman spectroscopy?
