This chapter focuses on rotational spectroscopy. Despite the limitation of a gas phase-only observation, rotational spectroscopy provides a wealth of information concerning molecules, especially with matters of precise bond lengths, bond angles, and dipole moments.

This chapter derives expressions for the rotational energy levels of diatomic and polyatomic molecules. It shows how to interpret rotational spectra, in which only the rotational state of a molecule changes. It also emphasizes how rotational spectroscopy provides very precise details of bond lengths and bond angles of molecules in the gas phase.

Collisions and rotational spectroscopy
Journal of Molecular Spectroscopy, 1992Abstract Motivated by Oka's early work on molecular collisions and especially collision-induced rotational transitions, this paper addresses progress in these areas. Particular attention is paid to recent extensions to lower energy collisions of astrophysical significance and to questions about the relation between experimental observables and the ...

Rotational spectroscopy meets theory
Physical Chemistry Chemical Physics, 2013Rotational spectroscopy is known to be a technique that is widely used to infer information on molecular structure and dynamics. In the last few decades, its role in the field of atmospheric and astrophysical investigations has rapidly grown. However, several are the challenging aspects in rotational spectroscopy, since the detection and analysis of ...

Vibration-Rotation Spectroscopy
Annual Review of Physical Chemistry, 1956Approximately four hundred titles pertaining to the topic of vibration rotation spectra appeared during the calendar year 1955 among the contents of the forty-three periodicals that we attempted to survey. Merely to list this bibliography without comment, in the conventional style, would con sume more than half of the printed pages assigned to this ...

This chapter cites a gas phase sample that demonstrates molecules in continual motion, appropriate to its thermal energy. It describes the continual motion of the molecules as rotational energy, which is the kinetic energy associated with the tumbling motion of the molecules relative to an observer in the laboratory.

Rotational and vibrational spectroscopy
2015This chapter presents a brief introduction to rotational and vibrational spectroscopy. It explains how pure rotational spectroscopy can be used in the precise determination of molecular geometry in small molecules and provide a direct means to deduce the shape of larger molecules.
