The rotations distort the molecule and change r. The higher the rotational quantum number, J, the longer the molecule becomes. . Rotational spectroscopy is only really practical in the gas phase where the rotational motion is quantized. For a diatomic molecule the energy difference between rotational levels (J to J+1) is given by: \[E_{J+1}-E_{J}=B(J+1)(J+2)-BJ(J=1)=2B(J+1)\] with J=0, 1, 2,... Because the difference of energy between rotational levels is in the microwave region (1-10 cm-1) rotational spectroscopy is . While there have been some important refinements in the theory of diatomic molecular spectra, most of the advances have been in the further exploration of individual spectra. The book provides an important opportunity for students to learn the core concepts of physics and understand how those concepts apply to their lives and to the world around them. .

Lineshape Functions. Rotational spectroscopy measures a high-resolution spectrum where the spectral pattern is determined by the three-dimensional structure of the molecule [6]. Written to be the definitive text on the rotational spectroscopy of diatomic molecules, this book develops the theory behind the energy levels of diatomic molecules and then summarises the many experimental methods used to study their spectra in the gaseous state. H-H and Cl-Cl don't give rotational spectrum (microwave inactive).
