Resonance light scattering curves

Molecular absorption or light scatter can be corrected for by several methods. If the interfering salt composition is known, it may be possible simply to add the salt or salts to standards and make a direct comparison with calibration curves. It is relatively simple to measure the background absorbance. One way is to choose a nonresonance line from the lead hollow cathode lamp or another lamp that is not absorbed by lead and which occurs at least two bandpasses from the resonance... 

The scattered light / was observed as a function of the scattering angle (k from -90° to 90° at intervals of 1.0° using photomulitiplier (PM). The incident angles for the scattered light measurements were set as the resonant angles of the ATR curves.
