Rotational spectroscopy and astrochemistry
Journal of Molecular Structure, 1995Abstract During the last 25 years, the close collaboration between laboratory spectrocopists and astrophysicists allowed the detection of about one hundred different molecular species in the interstellar medium, largely via their rotational emission spectra.

Abstract This chapter starts with a discussion of classical rotation of rigid bodies and moments of inertia. Asymmetric, symmetric, and spherical tops are defined. Rotational energy levels of diatomic and linear molecules are derived, along with selection rules and spectra. Rotational energy levels of symmetric tops are derived including

Vibration-Rotation Spectroscopy
Annual Review of Physical Chemistry, 1955Since the general background of vibration-rotation spectroscopy has quite recently been brought up to date in reviews of this series it seems possible to dispense with any general introduction to this subject. In this review it is proposed to indicate some present trends and to give a reasonably complete though not exhaustive account of recent ...

Quantum chemistry has nowadays reached such an advanced level that highly accurate results can be achieved for energies and properties of small to medium-sized molecules. For these high-level calculations the requirements are efficient treatment of electron correlation via coupled-cluster theory, basis-set extrapolation techniques, incorporation of ...
