From gross and specific selection rules below, identify which belongs to the rotational, rotational Raman, vibrational and electronic spectroscopies. Gross selection rules: The dipole moment must change during the transition Molecule must have permanent dipole moment Molecule must have anisotropic polarizability

Rotational spectroscopy, the dipole moment must change during the transition.

Rotational Raman spectroscopy, molecule must have anisotropic polarizability

Vibrational and electronic spectroscopy, molecule must have permanent dipole moment.

Explanation:

For the vibration rotation spectrum to be observed, it is necessary to change the dipole moment during the vibration.Raman scattering using an anisotropic crystal gives information about the orientation of the crystal. The polarization of Raman scattering light relative to the crystal, and the polarization of laser light, can be used to determine the orientation of the crystal, provided the crystal structure is known.

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.

The answer is true for your question.
