Spectroscopic observation of the Faraday effect in the far infrared
Abstract:
The Faraday effect was observed in the far-infrared spectrum of NO(2) for what is believed to be the first time. A systematic investigation of the magneto-optical signal as a function of the uncrossing angle between the polarizers was performed. Differences from similar experiments performed in the infrared and the visible regions were encountered. Moreover, a fit of the experimental data allowed calculation of the difference in the real and the imaginary terms of the refractive index for DM(F)=+1 and DM(F)=-1 multiplets.

IR Spectrum
Transmittance is defined as the ratio of the radiant power passing through a sample to that from the radiation's source. Multiplying the transmittance by 100 gives the percent transmittance (%T), which varies between 100% (no absorption) and 0% (complete...
