In spectroscopy collision induced absorption and emission refers to spectral features generated by inelastic collisions of molecules in a gas such inelastic collisions along with the absorption or emission of photons may induce quantum transitions in the molecules or the molecules may form transient supramolecular complexes with spectral features different from the underlying molecules. Collision induced dissociation cid also known as collisionally activated dissociation cad is a mass spectrometry technique to induce fragmentation of selected ions in the gas phase the selected ions typically molecular ions or protonated molecules are usually accelerated by applying an electrical potential to increase the ion kinetic energy and then allowed to collide with neutral . 1 introduction considerable efforts have been devoted in recent years to the interpretation of the hneshape for collision induced absorption cia by molecular gases a typical example is given by the analysis of the far infrared absorption of n for which some simplifying assumptions seem to be reasonably well fulfilled. The induced spectra of rare gases in the far infrared are particularly simple but show characteristic features common to all collision induced absorption these will be considered first collision induced absorption spectra of pure monatomic gases like helium or argon have not been recorded. This book reviews the theory and experiment of collision induced absorption of infrared radiation in dense gases throughout the book the emphasis is on absorption by binary molecular complexes but read more
