Polarization spectroscopy of pendular molecules in the gas phase

Abstract

The orientation or alignment of pendular mols. gives rise to an optical anisotropy. The sparse resonance structure of polarization spectra of pendular mols. can be explored to elucidate their structure. A quant. simulation of the polarization spectra is possible at any field strength. Both the exptl. procedure and the simulation are demonstrated for the ICl mol., and an extension to large mols. is discussed.
