High-resolution polarization spectroscopy in the 10-micron range
Abstract
The paper deals with a sensitive technique of high-resolution laser spectroscopy based on light-induced birefringence and dichroism of an absorbing gas. Polarization spectroscopy is related to saturated-absorption spectroscopy, but offers a better signal-to-background ratio. The application of the technique to the investigation of the vibration-rotation band spectrum of SF6, NH3, CF2Cl2, and BCl3 molecules is described, and results obtained at CO2-laser wavelengths are examined.
