Suppression of coherent scattering by coherent population trapping on molecular vibrational levels

Abstract

Raman scattering has been studied in molecular media. The role of rotational levels has been investigated. It is shown that themolecular vibrational coherence stronglydepends on the effect of coherent population trapping for rotational levels. The obtained results are important for application of Raman spectroscopy to molecular detection for engineering, chemical, and biological applications.
