Molecular Symmetry and Group Theory - Carter. Authors: K. Veera Reddy. Molecular symmetry in chemistry describes the symmetry present in molecules and the classification of molecules according to their symmetry. The chapters are extensively illustrated and deal with such topics as symmetry elements, operations and descriptors, symmetry guidelines, high-fidelity pseudosymmetry, crystallographic symmetry, molecular gears, and experimental techniques, including X-ray crystallography and NMR spectroscopy. In spectroscopy the changes in transition peak intensities resulting from couplings between eigenstates of a zeroth-order Hamiltonian is called intensity borrowing,

For the triatomic molecule H2Se at large values of the quantum numbers J and Ka, the rotation-vibration energies form sets of four, almost degenerate levels, so-called four-fold clusters. The chapters are extensively illustrated and deal with such topics as symmetry elements, operations and descriptors, symmetry guidelines, high-fidelity pseudosymmetry, crystallographic symmetry, molecular gears, and experimental techniques, including X-ray crystallography and NMR spectroscopy.

This textbook explains the use of the molecular symmetry group in understanding high resolution molecular spectroscopy.
Rotational spectroscopy is concerned with the measurement of the energies of transitions between quantized rotational states of molecules in the gas phase. The spectra of polar molecules can be measured in absorption or emission by microwave spectroscopy  or by far infrared spectroscopy. The rotational spectra of non-polar molecules cannot be observed by those methods, but can be observed and measured by Raman spectroscopy. Rotational spectroscopy is sometimes referred to as pure rotational spectroscopy to distinguish it from rotational-vibrational spectroscopy where changes in rotational energy occur together with changes in vibrational energy, and also from ro-vibronic spectroscopy or just vibronic spectroscopy where rotational, vibrational and electronic energy changes occur simultaneously.

It seems that you're in Germany. We have a dedicated site for Germany. The aIm of the present article is to give a critical exposition of the theory of the symmetry properties of rigid and nonrigid molecules. Despite the fact that several accounts of the subject, both technical and didactic, are now available, and despite the extensive discussion of nonrigid molecule symmetry that has been going on since the classic papers of Hougen and Longuet-Higgins, there remains a need for a unifying survey of the problem. Previous treatments have tended to emphasize one or the other particular viewpoint at the expense of a broader view. As is shown below, analogous insights can also be obtained in the case of nonrigid molecule symmetry, where the Eckart-Sayvetz conditions provide a natural generalization of the Eckart constraints.
