Laser Double-Resonance Spectroscopy in Molecular Physics

  • W. Demtröder
Part of the NATO ASI Series book series (NSSB, volume 119)


Detailed experimental investigations of electronic transitions in diatomic or polyatomic molecules and closer examinations of excited molecular states are often impeded by fundamental difficulties: The visible and ultraviolet spectra of many molecules show an exceedingly high spectral line density where many lines overlap within their Doppler-width. The application of “classical”, Doppler-limited spectroscopic techniques to such cases often yields quasicontinuous spectra concealing many finer details such as rotational structure or fine- and hyperfine splittings. Furthermore, the excited states of molecules often have a perturbed level structure which results in congested and irregular spectra and makes their assignment a tedious task.
